Its chemical formula is ZnS. Its molecular weight, 134.72. The zinc ions, Zn2+ and sulfur ions, S2- are able to interact through ionic interactions. The sulfur ions form a regular tetrahedron in which the zinc ion sits in the middle. The sulfur ion occupies the center of the tetrahedron. This structure can also be described as a facecentered cubic system where zinc and sulfur are located in the vertex of the crystal and at the center of the face.
Zinc Sulfide (also known as Zinc Sulfide) is an insoluble, white solid. It is not soluble in water. However, it is soluble with bases and acids. Zinc sulfide's density is 3.98 g/cc, with a melting and boiling temperature of 1 350 degrees C. The light transmission range of zinc sulfide is between 200 and 400nm. Zinc sulfide has relatively stable properties, but under certain circumstances it can react. Zinc sulfide is oxidized, for instance, when it comes into contact with an oxidizing substance. In an environment that is alkaline, zinc hydroxide can be formed by the reaction of 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 has many uses, including in fluorescent screens. 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 used 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 many applications in pharmaceutical production. Zinc sulfide is used in the manufacture of anti-malarials, including zincsulfate as well as zinc acetate. The zinc sulfide used can be used for the production of preservatives, fungicides as well as other products.
4. Catalyst Manufacturing
Zinc sulfide can act as a catalyst for the creation of other compounds like zinc acetates, acetones, 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.
Method of Production 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.
Preparation Solution: 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 a large number of 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 reactions. A solid reaction between zinc oxides and sulfur-containing elements was used to produce zinc sulfide.
Ingredients: To make raw materials, the appropriate amount of carbon powder, zinc oxide powder, and sulfur dioxide powder is mixed.
Pretreatment - The raw materials undergo a pretreatment at high temperature to ensure that all components react and generate zinc and sulfide vapor.
Synthesis: Zinc and sulfur vapors are produced at high temperatures.
Collection: The powdered zinc sulfide is collected and processed accordingly.
The high-temperature, solid-phase synthesis is characterized by high purity, excellent crystallinity, as well as a relatively straightforward process. The method does require high-temperatures and a lot of carbon and sulfur powders, which can cause some environmental pollution.
3. Solventothermal Method
The solvothermal process is a method that has been developed to prepare zinc sulfide. The method is to dissolve zinc salts and sulfur salts in organic solvents under high temperature and pressure, and then generate zinc sulfide by hydrothermal reactions.
Solution preparation: Dissolve a suitable amount of zinc salt and sulfur in an 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.
The generated zinc powder is collected, and treated as required.
The solvothermal technique has a number of advantages including a high degree of product purity, good crystalline quality, and comparatively simple processing. To regulate product properties, this method uses different organic solvants and reaction conditions. 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 the environment and humans.
