What is Zinc Sulfide ZnS Product?

Overview of Zinc Sulfide ZnS Powder

Zinc sulfide is an inorganic compound with the chemical formula ZnS. It is a white or yellowish powder that darkens when exposed to sunlight. It is stable in dry air, and will gradually oxidize into zinc sulfate in humid air for a long time. It is usually formed by the action of hydrogen sulfide and zinc salt solution. Zinc sulfide has excellent fluorescence effect and electroluminescence function. In particular, nano-zinc sulfide has a unique photoelectric effect and exhibits many excellent properties in the fields of electricity, magnetism, optics, mechanics, and catalysis.

Physical and chemical properties of zinc sulfide ZnS powder

The chemical bond between Zn and S of zinc sulfide tends to be a covalent bond. The crystal has three different configurations: low temperature type, that is, sphalerite structure, abundant in nature, colorless cubic crystal, Zn, S coordination number is 4, relative density is 4.10. 1020 ℃ High temperature type; high temperature type, namely wurtzite structure, colorless hexagonal crystal, Zn, S coordination number of 4, relative density 3.98, melting point about 1700 ℃. High temperature stable structure of zinc sulfide; high pressure type, namely chloride In the sodium structure, the coordination number of Zn and S is 6, and the relative density is 5.21. There is also a water-based compound, ZnS·H2O, which is a white powder with a relative density of 3.98 and a melting point of 1049 °C. Zinc sulfide is insoluble in water and dilute alkali, insoluble in acetic acid, but soluble in low-concentration strong acids such as hydrochloric acid, releasing hydrogen sulfide. The solubility product of zinc sulfide is similar to the K1·K2 value of hydrosulfuric acid, so the following equilibrium exists in dilute acid:

Zn2+H2S=2H+ZnS

It can be seen that in the strong acid zinc salt solution, the hydrogen sulfide gas cannot obtain zinc sulfide precipitation. Passing hydrogen sulfide gas into the zinc salt solution can get zinc sulfide precipitation, but the precipitation is not complete. Using ammonium sulfide solution as precipitating agent, the zinc ions in the zinc salt solution can be completely precipitated into zinc sulfide. Since the ammonium sulfide solution is alkaline, the acidity of the system can be reduced. In industry, the above method should be used to isolate the air. White zinc sulfide darkens when exposed to light, and is easily oxidized to zinc sulfate in the air. Zinc sulfide can be used alone as a white paint pigment or in combination with zinc oxide. Pure zinc sulfide does not emit light. If a trace amount of manganese, copper, and silver are added to the zinc sulfide crystal as an activator, it can emit different colors of fluorescence after being illuminated, called phosphor powder, which is used to make fluorescent screens and luminous paints. Zinc sulfide is also used in leather, enamel, rubber, dye and other industries.

Zinc sulfide is corrosive and toxic. It can irritate the skin. Operators should wear work clothes and protective equipment. The workshop should be well ventilated.

Application of Zinc Sulfide ZnS Powder

1. It can be used as analytical reagent, phosphor matrix, photoconductor material; or used in the manufacture of dyes, coatings, pigments, glass, curing oil, etc.

2. Zinc sulfide is widely used in the production of infrared windows, fairings, and infrared optical components. It has the characteristics of high purity, insoluble in water, moderate density and easy processing. Zinc sulfide has good refractive index uniformity and consistency. It has good image transmission performance in the 8-12μm band, but some parts start to absorb after 10um. In the mid-infrared, transmission is higher, and absorption and scattering increase with shortening of wavelength. Zinc sulfide is highly resistant to harsh environments, with twice the hardness and breaking strength of zinc selenide.

Robust front optics for zinc sulfide thermal imaging systems in the infrared window and thermal band (8 to 14 μm).

Single crystal zinc sulfide is available, but not common. In the usual spectral range, the scattering is very low. It can be used as a high-power laser device under the condition that the bulk absorption and internal structural defects of the material are strictly controlled, and the polishing technology with minimal damage and the coating technology with the highest optical quality are used.

Zinc sulfide oxidizes significantly at 300 ℃, plastic deformation occurs at about 500 ℃, and dissociation occurs at about 700 ℃. For safety reasons, zinc sulfide windows should not be used in normal environments above 250°C.

3. For optical coating targets, X-ray screens, luminous dials with trace amounts of radium or neodymium salts added, TV screens, and paint pigments.

Tungsten oxide overview

Tungsten trioxide is a powder metallurgy raw material for the production of cemented carbide and tungsten products. According to the national standard (GB/T 3457-1998), it is divided into two types, namely tungsten trioxide (referred to as yellow tungsten), molecular formula is WO3, and blue tungsten oxide (referred to as blue tungsten, is a mixed tungsten oxide), molecular formula W20O58. Yellow tungsten is light yellow crystalline powder, blue tungsten is dark blue or blue-black crystalline powder.

Preparation method of tungsten oxide

1. Ammonium tungstate method: The tungsten concentrate is hydrolyzed by sodium hydroxide, neutralized with hydrochloric acid, and then reacted with ammonium chloride to generate ammonium tungstate, which is then added with hydrochloric acid for acid hydrolysis to generate tungstic acid, which is then decomposed by roasting. , pulverized to obtain tungsten trioxide.

2. Hydrochloric acid decomposition method of tungstate. The saturated aqueous solution of sodium tungstate Na2WO4, calcium tungstate CaWO4 and other tungstate salts is heated, and the solution is slowly added dropwise into 2-3 times excess boiling concentrated hydrochloric acid by molar ratio. According to the above reaction, yellow tungstic acid is precipitated. At this time, if the dripping speed is too fast or the liquid temperature drops, suspension or colloidal precipitation is likely to be formed, which brings difficulties to the next treatment. After the dropwise addition, heating was continued on a water bath for 1 h, and the precipitate became easy to filter. After standing, it was washed several times with 5% ammonium nitrate aqueous solution to completely remove Cl-. After filtration, it is dried at 120 °C, and finally heated to 600 °C, the tungstic acid is completely dehydrated and becomes tungsten trioxide.

3. Thermal decomposition of ammonium paratungstate. Put ammonium paratungstate (NH4) 10W12O41·11H2O purified by recrystallization method into a porcelain crucible, and when heated to above about 400 ℃, ammonia volatilizes to obtain tungsten trioxide.

Chile's government has decided to create a state-owned lithium enterprise and hopes to establish a model for the company by the end of the year, Mining Minister Marcela Hernando said in an interview.  

Chile is the world's second largest lithium producer and has the largest reserves of lithium in the world. The domestic lithium industry is currently dominated by two private companies, Albemarle and SQM.  

Chile wants to participate more closely in the booming lithium market after leftist President Gabriel Boric took office in March. The accelerating electrification of the global auto industry has helped push prices of lithium, a key raw material for electric car batteries, to record highs over the past year, lapping up more players, including Mexico and Argentina, who want a piece of the market.  

According to Hernando, the government is setting up a task force to determine the best way to run state-owned lithium enterprises. She said the government hopes to establish plans by the end of the year for how the company will develop and what business model it will operate under. 

Hernando stressed that while the state would be a major shareholder in the proposed company, it was open to private investment.

Why does properly poured concrete end up cracking

It is very easy to cause concrete cracking if the construction or maintenance are not done correctly. What are then the five main causes of cracking concrete?

1. Some construction workers add more water in order to improve the fluidity, but this will result in an increase in water-cement, which leads to concrete cracking.

2. Transport and mixing issues: If mixing and transporting concrete takes too much time, the water in the concrete will evaporate quickly. concrete . This leads to a concrete that is weaker on the construction site, unable to meet construction specifications.

3. Construction speed

4. Maintenance is unreasonable. During the period of maintenance, if late watering isn't maintained, the result will be the Cracking phenomenon Later in the year, concrete will be used. Concrete is used in the future. Concrete Surface Watering You can water the concrete often to speed up the drying process. Concrete will shrink drastically if it is not watered. Late cracking occurs when concrete strength is decreased.

5. Environmental factors: If the environment at the construction site is relatively dry and there is high temperature, wind, or both, then the evaporation rates of the surface concrete are accelerated. This results in cracking on the surface. Concrete constructions are most likely to crack in summer or winter due to the temperature difference.

Solution: Add anti-cracking agents, a variety inorganic materials composite anticracking agent can stop more than 80% cracking of foam concrete, add 2-3 kg per cubic meter.
