 Silicon Sulfide Information:

SiS2 is a molecular formula for silicon sulfide. When moisture is present, white fibrous orthorhombic and tetragonal Crystals decompose to SiO2 and H2S. It is a flammable substance when heated.


Silicon Sulfide SiS2 Particles:

Silicon-sulfide, an inorganic chemical compound with a molecular formula of SiS2, is a colorless acicular crystal. SiS2 is a colorless, acicular crystal. Its relative density equals 2.02, its melting point is 1090, and at 1250, it sublimates to nitrogen. Insoluble in benzene; Soluble in dilute base. Hydrolysis and Ammonolysis were caused by water, ethanol, or liquid ammonia. The reaction of alkali metal sulfides with thiosilicates.

siS2 decomposes easily to produce hydrogen sulfide, just like other silicosulfide substances, such as bis (trimethylsilyl sulfides). It was reported that in liquid ammonia it can form the imide Si (NH)2 or NH4SH. Recent reports, however, have identified (NH4)2[SIS3(NH3)]*2NH3 containing the tetrahedral anion, SIS3(NH3).

By reaction with ethanol, tetraethyl and orthosilicate were produced. Alcoholysis was carried out with a large amount of tertbutyl ethanol to produce tri (tertbutyl) silicon mercaptan.

What is the production process of Silicon Sulfide (SiS2) Powder?
Direct synthesis method:

The direct synthesis method is the direct synthesis of silicon sulfide from silicon and sulfur under high temperatures and pressure. In this method, pure silicon and sulfur raw materials are usually heated to high temperatures (usually between 1000-1500 ° C) in a high-pressure furnace and kept in a sealed furnace chamber for some time to allow the silicon and sulfur to react to produce silicon sulfide. The resulting silicon sulfide particles are collected and processed to produce the desired product. This process can control the particle size, purity, and crystal structure of the product by controlling the heating rate, reaction time, and reaction atmosphere.

The advantage of this method is that it is simple and easy to obtain raw materials and is relatively cheap, so it has a low production cost. However, due to the conditions of high temperature and high pressure, the requirements for equipment and technology are high, and a strict quality control system is also required to ensure the quality and stability of products.

Chemical vapor deposition method:

Chemical vapor deposition (CVD) is a method of deposition and growth of silicon sulfide film on substrate by chemical reaction. In this method, a compound containing silicon and sulfur elements, such as silicon tetrachloride and sulfur vapor, is introduced into a high-temperature reaction chamber, where a chemical reaction occurs to produce silicon sulfide, which is deposited on the substrate. The structure, purity, and thickness of the deposited film can be controlled by controlling the reaction temperature, gas flow, and the position of the substrate.

The advantage of this method is that it can be carried out at normal temperature and pressure, which is suitable for large-scale production, and the deposited film has high quality and performance. However, due to the need to use high-temperature furnaces and precision-controlled equipment, the requirements for technology and equipment are high, and the production cost is also high.

Silicon Sulfide SiS2 SiS2 Powder
Silicon sulfide can be used as a source of silicon that is compatible with sulfates. Sulfate, also known as a sulfate ester, is formed when one or more hydrogens are replaced with metal.
