Silicon Sulfide Information:

SiS2 is a molecular formula for silicon sulfide. When moisture is present, white fibrous orthorhombic and tetragonal Crystals decompose to SiO2 andH2S. 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 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. Reaction of alkali metalsulfides with thiosilicates.

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

By reaction with ethanol, tert-butyl mercaptan and H2S are obtained. Alcoholysis was carried out with a large amount of tertbutyl alcohol in order to obtain the tri (tertbutyl-silicate) silicon mercaptan.

Reaction of sodium sulfide with magnesium sulfide & aluminum sulfide gives sulphosilicate.

What is the production process of Silicon Sulfide (SiS2) Powder ?

1. Burn aluminum powder in the crucible with extra sulfur. The aluminum sulfide mixture is crushed with a little excess silica. Mixture is put in a shingle. Place the shingle into a quartz tube and heat it while injecting some dry nitrogen. The reaction starts around 1100. At 1200 to 1300, the sublimated Sis2 will adhere to the lower temperature region of the quartz tube. After purification, it’s sublimated in nitrogen or vacuum. You can prepare tetragonal Sis2 by heating the silicon-sulfur mixture at 5x103MPa 700.

2. Add sulfur to decompose the silicon at a low temperature. By heating 96g sulfur and 39g Si(SC2H5)4 for 10 minutes at 200°C, you can produce Si-disulfide. The latter is then dissolved in benzene.

Applications 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.

Storage condition of Silicon Sulfide (SiS2) Powder:

Silicon Sulfide SiS2 is affected by dampness, which will have an adverse effect on the performance of SiS2 powder and its use. Silicon Sulfide SiS2 must be packed in vacuum and kept in a room that’s cool and dry. Silicon Sulfide SiS2 should not be exposed to stress.

Packaging & Shipping Silicon Sulfide (SiS2) Powder:

The packing is dependent on the amount of Silicon Sulfide SiS2 POWDER.

Silicon Sulfide (SiS2) Powder packaging: vacuum packed, 100g,500g or 1kg/bag; 25kg/barrel. Or as per your request.
