Its chemical formula is ZnS. The molecular weight of the compound is 134.72. It is created by interacting through ionic interactions with zinc ions, (Zn2+), and sulfur ions, (S2-). The sulfur ions form a regular tetrahedron in which the zinc ion sits in the center. In contrast, the ion sulfur is found in the center of the tetrahedron. This structure can also be described as a face centered cubic crystal system where zinc and sulfur ions are located at the vertex and center of the face, respectively.
Zinc Sulfide (also known as Zinc Sulfide) is a white, insoluble solid. It is not soluble with water, but it is soluble with bases and acids. Zinc sulfide’s density is 3,98 grams per cubic centimeter, with a melting and boiling temperature of 1 350 degrees C. The light transmission range of zinc sulfide is between 200 and 400nm. Its chemical properties are stable but under certain circumstances it can also change. zinc Sulfide is oxidized by an oxidizing substance to produce zinc sulfate. In an environment that is alkaline, zinc hydroxide can be formed by combining zinc sulfide with hydroxide.
Application Of Zinc Sulfide
Zinc sulfide, also known as zinc sulfur, is a significant compound. The unique crystal structure and chemical and physical characteristics of zinc sulfide have made it a widely used compound in many fields. We will discuss the various applications of zinc sulfide.
1. Manufacturers of phosphor
Zinc Sulfide is a widely used phosphor, particularly in the production of fluorescent screens. It also has many applications for fluorescent lamps. Zinc sulfide, used in the manufacture of fluorescent screens, can be made into phosphors, which can then emit light to display an image when they are excited by external lights. In the manufacture of fluorescent lamps, zinc-sulfide also makes phosphors which emit visible light upon being excited by ultraviolet radiation.
2. Manufacturing of photoelectric conversion materials
Zinc Sulfide, a material important for photoelectric conversion, can also be used in the manufacture of solar cells. Zinc sulfide converts light energy into electrical power in solar cells. The photoelectric efficiency of zinc sulfide, combined with its low cost, makes it a material that has wide applications.
3. Drug Manufacturing
Zinc Sulfide, because of its biological activity has certain applications in pharmaceutical production. Zinc sulfide is used in the manufacture of anti-malarials, like zinc sulfate, and zinc acetate. zincsulfide may also be used for the production of preservatives or fungicides.
4. Catalyst Manufacturing
Zinc sulfide can act as a catalyst for the creation of other compounds like zinc acetate, Acetone and methylisobutylketone. Zinc sulfur is a highly active and selective catalyst in manufacturing.
5. Optical device manufacturing
Due to its high transparency, zinc sulfur is used widely in optical devices. Zinc sulfide is used, for instance, in optical fiber communication to produce optical fiber preforms. Additionally, zinc sulfide may be used to make optical devices like optical Windows and lenses.
Production method of Zinc Sulfide.
1. Method of chemical precipitation
The chemical precipitation method is the most common way to prepare zinc sulfide. The zinc sulfide was obtained by mixing zinc salt with sulfur salt in solution.
Solution for preparation: Dissolve a suitable amount of zinc salt and sulfur salt into water to create a solution.
Precipitation reaction : the above solution is heated in stirring conditions and a precipitating agent of appropriate amount is added to precipitate sulfur ions as well as zinc ions. This results in zinc sulfide.
Filtration : The reaction is filtered in order to obtain a filtrate that contains zinc-sulfide precipitation.
Cleaning: The filtered precipitation of zinc sulfide is cleaned with alcohol in order to remove impurities.
Drying: After washing the zinc sulfide it is precipitated then dried to get zinc sulfide.
Chemical precipitation is easy to do, inexpensive, and produces a product of high purity. The disadvantages of this method are that it requires many detergents and precipitating agents. Also, the waste liquid generated must be further processed before being discharged, which can cause environmental pollution.
2. Synthesis of solid phases at high temperatures
Traditional methods for the preparation of zinc sulfide include high-temperature solid-phase synthesis. A solid reaction between zinc oxide or sulfur-containing elements and zinc at high temperature produced the powdered form of zinc sulfide.
Ingredients: To make raw materials, the appropriate amount of carbon powder, zinc oxide powder, and sulfur dioxide powder is mixed.
Pretreatment: Raw materials undergo a pretreatment at high temperature to ensure that all components react and generate zinc and sulfur vapour.
Synthesis: Zinc and sulfur are combined at high temperature to form zinc sulfide.
Collection: The powdered zinc sulfide is collected and processed accordingly.
High-temperature, solid-phase synthesis is characterized by high purity and good crystallinity. The process itself is relatively simple. The method does require high temperatures, and it uses a lot of carbon and sulfur powders, which can be harmful to the environment.
3. Solventothermal Method
The solvothermal process is a method that has been developed to prepare zinc sulfide. This method uses high-pressure and high-temperature organic solvents to dissolve zinc and sulfur salts. It then generates zinc powder by hydrothermal reaction.
Preparation Solution: Dissolve an appropriate amount of zinc salt and sulfur in organic solvent.
High temperature and pressure reaction: The solution above will be placed in a high temperature and pressure reactor. Under these conditions, the hydrothermal reactions will produce zinc sulfide.
Collection: The generated powder of zinc sulfide will be collected and treated as required.
The solvothermal technique has the advantage of a high purity product, good crystallinity as well as a relatively straightforward process. Moreover, it is possible to use different organic solvants and reaction conditions in order to regulate product properties. The method is not without its limitations. It requires high-temperature, pressure equipment. And the recovery and disposal process of organic solvents are expensive and require certain technology.
It is important to consider the advantages and limitations of different methods of production of zinc sulfide, and to select the appropriate methods according to actual conditions and needs. During the production, it is important to take into account environmental protection and safety. Adopting appropriate environmental protection technologies and measures will help reduce the harm caused to humans and the planet.
