Silicon Sulfide Information:
Silicon sulfide has the molecular form SiS2. At normal pressure, white fibrous orthorhombic crystals or tetragonal crystals remain stable and can be decomposed to SiO2 (or H2S) in the presence moisture. If heated in air, it burns.

Silicon Sulfide SiS2 powder:
Silicon sulfur, an inorganic compound has the molecular structure SiS2. 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 water, liquid ammonia 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, such imides have been identified as Si(NH),2 and NH4SH. Recent reports however identify crystallization (NH4)2[SIS3 [NH3)]*2NH3) as a product containing a tetrahedral 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 alcoholyze tri (tert butyl) silicon mecaptan.

How Silicon Sulfide Silica SiS2 Puffer is produced?
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 5x103MPa 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–S2-C2H5, c2H5–C2H5–S3–C2H5). This is then dissolved in benzene, and the mixture is filtered to avoid it mixing with water.

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 sulfate can be replaced by a metal to make 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 to 500g or one kg/bag at 25kg/barrel. Or as you request.
Silicon Sulfide SiS2 Pudding shipping: Could be shipped by sea, air or express as soon after receipt of payment.
