What is Zinc Sulfide

Zinc Sulfide:

Its chemical formula is ZnS. Its molecular weight, 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 middle. 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 lattice.

Zinc Sulfide (also known as Zinc Sulfide) is a white, insoluble solid. It is not soluble in water. However, 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 react. 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.

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 salts in a liquid solution.

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.

After washing the zinc sulfide it is dried and precipitated 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, resulting in some 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 of sulfur oxides and zinc at high temperature produced 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 material is pretreated at high temperature to ensure that all components react and generate zinc vapor.

Synthesis: Zinc and sulfur are combined at high temperature to form zinc sulfide.

The zinc sulfide synthetic powder is collected.

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 it uses a lot of carbon and sulfur powders, which can be harmful to the environment.

3. Soluthermal 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 pressure and temperature. This produces zinc sulfide by hydrothermal reaction.

Preparation Solution: Dissolve an appropriate amount of zinc salt and sulfur in organic solvent.

High temperature and pressure reaction: In a high-temperature, high-pressure reactor the solution above is placed and hydrothermal reaction takes place under conditions of high temperatures and high pressures to produce zinc powder.

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 and a relatively straightforward process. The method is also capable of using 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 and safety issues and implement appropriate environmental protection technologies.

ZnS can be found in two main types of crystals. The prominent example of the polycrystalline duality is typically one that contains ZnS. Each form has a tetrahedral coordination geometry. The stable cubic form, also known as sphalerite, is also known. The mineral wurtzite is the hexagonal form. However, it can also be synthesized synthetically. At around 1020degC, the transition between sphalerite and wurtzite is made. The tetragonal form of sphalerite is also known as a rare mineral called lithium manganese. It has the formula (Zn Hg) S.

For what is Zinc Sulfide Zinc SnS used?
Zinc sulfuride is used mainly in paint and plastics for chemical production. Zinc sulfide has become an important pigment in paint due to its white opaqueness and insolubleness in water, organic solvents and weak acid and weak base. Zinc sulfuride, which is the second most important pigment in America after titanium dioxide, still plays an important role in European industries.
Zinc sulfide has a melting point of 1650. The Mohs toughness of 98% of the commercial-grade zinc is 3.0. The refractive index, 2.37. Due to its high wear resistance and refractive index, zinc sulfide is a good choice for equipment, wax paper and metal plates with thin layers.
Zinc sulfuride is easy and simple to disperse. It is a neutral-white metal with excellent optical properties. It is commonly used as a component in thermosetting plastics and thermoplastic plastics.

Luminescent Material
Zinc sulfuride is a mixture of zinc sulfide and a few parts per million of a suitable activator. It exhibits strong phosphorescence, as described by Nikola Tesla, in 1893. This product can be used in many applications including X-ray screens, cathoderay tubes, and products that glow in darkness. The result is bright blue when silver is used as an activater. The maximum size is 450 nanometers. Manganese is used to produce an orange-red color with a maximum size of 590 nanometers. Copper glows brightly for long periods of time and gives off a familiar green glow. In electroluminescent panels, copper-doped zinc Sulfide (” ZnS + Cu “) can also be used. It also displays phosphorescence from impurities that are exposed to blue and ultraviolet light.

Optical material
Zinc sulfuride can also serve as an infrared optical medium, transmitting at just 12 microns between visible wavelengths. You can either use it flat as an optical window, or as a lens. It is manufactured by synthesizing hydrogen sulfur gas and zinc vapour on a microchip. This product is FLIR grade (forward looking infrared), in which zinc sulfide can be found in an opaque milky yellow color. Cleartran is a transparent material that can be transformed under high isostatic pressure (HIPed). IRTRAN-2 was the name of the early commercial form, but it has since been dropped.

Pigment
Zinc sulfide can be called Sachtolith. Zinc sulfide can form lithopone when it is combined with barium-sulfate.

Catalyst
Fine ZnS is a high-efficiency photocatalyst which produces hydrogen gas under light. In the synthesis of zinc sulfuride, sulfur vacancies is introduced. This makes the ZnS gradually brown and increases light absorption.

Semiconductor characteristic
Both wurtzite, and sphalerite have a wide band-gap. These are IIVI semiconductors typical that have structures similar to other semiconductors such as gallium arsenide. The band gap between the hexagonal and cubic forms of ZnS is approximately 3.91 EV at 300 Kelvin. ZnS is available in both n- and P-type doping.
