Overview of silicon sulfide SiS2 powder:
Silicon sulfide is an inorganic compound with the molecular formula SiS2. White fibrous orthorhombic or tetragonal crystals. The relative density is 2.02, the melting point is 1090°C, and it sublimates in nitrogen at 1250°C. Insoluble in benzene; soluble in dilute alkali. Silicon sulfide is stable under normal temperature and pressure and decomposes into SiO2 and H2S when exposed to moisture. It burns when heated in the air.
Water, ethanol, and liquid ammonia are used for hydrolysis and ammonolysis respectively. Reacts with alkali metal sulfides to form thiosilicates. Like silica, this material is also polymerized, but the one-dimensional structure it uses is different from the usual silica form.
Like other silicon disulfide compounds (such as bis(trimethylsilyl) sulfide), SiS2 is prone to decomposition to release hydrogen sulfide. In liquid ammonia, it is reported to form imide Si(NH)2 and NH4SH, but recent reports have identified the crystal (NH4)2 [SIS3(NH3)]·2NH3 as a tetrahedral orthosilicate anion SIS3( NH3) product).
Synthesis of tetraethyl orthosilicate and H2S by reaction with ethanol. Carry out alcoholysis with a large amount of text-butanol to obtain tri(tert-butyl)silicon mercaptan:
3(CH3)3COH + Sis2→[(CH3)3CO] 3Sish + H2S
Silicon sulfide reacts with sodium sulfide, magnesium sulfide, and aluminum sulfide to produce sulfosilicate.
Application of silicon sulfide SiS2 powder:
What are the applicable scopes of silicon sulfide SiS2 powder?
Silicon sulfide SiS2 powder is an acid-soluble source of medium water and used for compatibility with sulfates of silicon. Sulfates are sulfates or esters formed by replacing one or two hydrogens with metals. Widely used as potting and molding materials. After various electronic and electrical components are coated and potted with room temperature vulcanized silicone rubber, they are widely used for sealing in the automobile and machinery industries, shock-resistant materials, rubber roller materials in the textile, plastic, and printing industries, and caulking and sealing materials in the construction industry. .At the same time, it can be used to make soft molds and molds for casting epoxy resin, polyester resin, polystyrene, polyurethane, vinyl plastic, paraffin wax, low melting point alloy, etc. In addition, the simulation performance of two-component room temperature vulcanized silicone rubber can replicate various exquisite patterns on cultural relics.
