Silicon Sulfide Information:
Silicon sulfide has the molecular form SiS2. At normal temperatures and pressure, white fibrous orthorhombic crystals or tetragonals can remain stable and will eventually decompose to SiO2 in the presence moisture. If heated in air, it burns.
Silicon Sulfide SiS2 powder:
Silicon sulfur, an organic compound with SiS2 molecular formula is an organic compound. SiS2 = 92.21. This is an inorganic compound with the molecular structure SiS2. Insoluble in benzene; Soluble in dilute base. Ammonolysis and hydrolysis were performed with liquid ammonia (ethanol), water and ethanol. Hydrolysis and ammonolysis occurred with water, ethanol, and liquid ammonia, respectively.
SiS2 can be easily decomposed to produce hydrogen sulfide, just like the other silicosulfide compound, bis (trimethylsilyl). Although it is known to form silica in liquid ammonia, and then NH4SH imide, there have been recent reports that the crystallization (NH4)2 [SIS3(NH3)]2NH3 was a product which contains the trihedral orthosilicate anion SIS3:NH3.
By reacting with ethanol, tetraethyl orthosilicate was synthesized and H2S was created. A large amount of tert butyl alcohol can be used to alcoholyse tri (tertbutyl), silicon mercaptan.

How is Silicon Sulfide Silica SiS2 Puffer made?
1. In a crucible, combine aluminum powder with excess sulfur and heat it until you get aluminum sulfide. You will then mix the aluminum sulfide and a small amount of silica with water. Mix the ingredients in a bag and place in a piece of shingle. Heat the tube with a little dry nitrogen, and then heat it. It starts at 1100 and the Sis2 sublimated adheres to the region at low temperatures at 1200-1300. After purification, the Sis2 is again sublimated with nitrogen or vacuum. The mixture of sulfur and silicon can be heated at 5103 MPa or 700 to make Tetragonal Sis2.
2. Heat silicon self-based silicon to decompose. By mixing 96g of sulfur with 39g Si(SC2H5)4 for 10 min, si-disulfide or ethylthioane are formed (C2H5-6-S2-C2H5,C2H5-6-C2H5,C2H5-6-C2H5,C2H5-6-C2H5). This is then dissolved in benzene, and the residue is filtered to avoid it mixing with water.
Applications of Silicon Sulfide SiS2 Silicon Sulfide SiS2 Pulver .
Silicon sulfide can be used as a compatibility agent with sulfates. It is medium-water and acid-soluble. One or more of the hydrogens in a metal can be replaced by a sulfate.
Silicon Sulfide SiS2 Pulp Storage:
SiS2 powder’s dispersion and usage performance will be negatively affected by damp reunion. Silicon Sulfide SiS2 should be stored in vacuum-packed bags and kept dry. Silicon Sulfide SiS2 Dust must not be exposed to air. Additionally, Silicon Sulfide SiS2 Pulver should not be exposed to extreme stress.
Shipping and Packing of Silicon Sulfide SiS2 Pulp:
There are many packing options available depending on the amount of Silicon Sulfide SiS2 Pulver.
Silicon Sulfide siS2 Powder packaging:Vacuum packing 100g, 500g or one kg/bag 25kg/barrel. Or as you request.
Silicon Sulfide SiS2 Pudding shipping: Could be sent out by air or sea as soon after receipt of payment.
