High Purity Zinc Sulfide ZnS Powder CAS 1314-98-3, 99.99%

Description of Zinc Sulfide：

Zinc sulfide is an inorganic compound with the formula ZnS. It is a white or yellowish powder, insoluble in water and soluble in acid. This compound is common in nature but is usually found in the form of zinc sulfide ore.

The crystal structure of zinc sulfide is a hexagonal crystal system, which is composed of Zn2+ and S2- ions. This compound has a molecular weight of 123.3, a melting point of 1700°C, and a thermal decomposition temperature of 1650°C. The hardness of zinc sulfide is not high, and it is easy to oxidize, but the oxidation rate is slower than that of ferrous sulfide.

Zinc sulfide plays an important role in geology and mineralogy. It is a common zinc mineral, mainly produced in lead-zinc deposits and copper deposits. Due to its low hardness and ease of mining and processing, zinc sulfide is widely used in a variety of industrial applications, such as ceramics, glass, coatings, pigments, rubber, batteries, etc.

In addition, zinc sulfide is also used to prepare other zinc compounds, such as zinc sulfate, zinc chloride, and so on. It can also be used in the making of a variety of zinc salts like zinc propionate, zinc acetate, zinc oxalate, etc. These zinc salts are widely used in medicine, pesticides, dyes, electroplating, and other fields. It is important to note that zinc sulfide is somewhat toxic, and long-term exposure or inhalation can cause health problems. Therefore, appropriate protective measures should be taken during production and use to avoid direct contact with and inhalation of this compound.

Zinc Sulfide Properties

Application of Zinc Sulfide：

Ceramic and glass industry: Zinc sulfide is a common ceramic pigment that can be used to produce ceramic products of various colors. In the glass industry, zinc sulfide is used as a clarifying agent to help remove bubbles and impurities from glass and improve its transparency and mechanical properties.

Rubber and coatings industry: Zinc sulfide is used as a white pigment in the rubber and coatings industry to give products excellent hiding power and whiteness. At the same time, it can also improve the weatherability, heat resistance, and corrosion resistance of the coating.

Battery manufacturing: In the battery manufacturing industry, zinc sulfide is used as a negative electrode material for batteries. This material has high conductivity and stability, which can improve the energy storage and life of the battery.

Pharmaceutical and pesticide industries: Zinc Sulfide has a versatile array of uses in the pesticide and pharmaceutical industries. It can be used as a drug carrier to help drugs be better absorbed and utilized by the human body. In terms of pesticides, zinc sulfide can be used as insecticides and fungicides to control crop diseases and pests.

Optical industry: Zinc sulfide has a high refractive index and scattering coefficient and can be used in the manufacture of optical components and instruments. For example, it can be used as a raw material for prisms and mirrors to improve the performance of optical devices.

Catalysts and adsorbents: Zinc sulfide has a high surface area and activity and can be used as catalysts and adsorbents. In chemical reactions, it can speed up the reaction rate and improve the selectivity of products. At the same time, zinc sulfide can also be used to absorb harmful substances in wastewater to achieve the purpose of purifying wastewater.

High-temperature superconducting materials: In recent years, the research of high-temperature superconducting materials has attracted wide attention. As a common superconducting material, zinc sulfide has potential application value in the field of high-temperature superconductivity.

Production Method of Zinc Sulfide：

Vulcanization method: The vulcanization method is one of the main methods of producing zinc sulfide. The method is to mix the zinc-containing raw material with the sulfur-containing raw material according to a certain proportion and react at high temperatures to produce zinc sulfide. During the reaction process, factors such as temperature, pressure, and raw material ratio need to be controlled to ensure the reaction and product quality.

Zinc oxide process: The zinc oxide process is another method of producing zinc sulfide. The method is to react zinc oxide with sulfur at high temperatures to produce zinc sulfide. The reaction also needs to control temperature, pressure, and other factors to prevent harmful gases generated during the reaction process from causing harm to the environment and the human body.

Direct synthesis method: The direct synthesis method is a method of directly synthesizing zinc sulfide. The method is to directly react zinc and sulfur at high temperatures to produce zinc sulfide. Direct synthesis is more expensive to produce and is mainly used for small-scale production in the laboratory or for special purposes.

Hydrometallurgy: Hydrometallurgy is a method of separating zinc and sulfur from ore by chemical reactions. This process converts zinc and sulfur in the ore into zinc sulfate and hydrogen sulfide gas, which is then produced by further chemical reactions. Hydrometallurgy is more expensive to produce but can process low-grade ores while also recovering other valuable metals.
