What does silicon disulfide mean?
Silicon disulfide It is an orthorhombic, or tetragonal white fibrous crystal system. SiS2 is silicon disulfide’s molecular formula. Normal temperature and pressure are stable for silicon disulfide. When exposed to moisture it will decompose into SiO2 (or H2S) and ignites when heated in the air.Silicon disulfide can be described as an inorganic compound. It has the chemical composition SiS2. Although similar to silica this polymer is also a material. However, its unique one-dimensional structure makes it different from silica.
What are the ingredients of silicon disulfide prepared?
1. Place aluminum powder, excess sulfur and a torch in a crucible. Burn to make aluminum sulfide. You will then need to crush the aluminum sulfide and add a little bit of silica. Combine the mixture in a large crockpot. Next, heat the crockpot while passing some dry nitrogen through the quartz tube. Reactions begin at 1100degC. At between 1200 and 1300degC the SiS2 is able to adhere to the tube at low temperatures. Purifying the mixture of silicon and sulfur can be done in either nitrogen or vacuum. For tetragonal SiS2, the mix of silicon and sulfur should be heated to 700degC at 5×103 MPa.2. To heat to make hydrocarbon sulfuride-based silicon. It can be decomposed at lower temperatures if it is mixed with sulfur. Combine 96g of Sulfur and 39g Si(SC2H5)4 in a bowl. Heat at 200C for 10 min to produce silicon disulfide (C2H5–S2-C2H5,C2H5–S3-C2H5). It is then dissolved into benzene. Then it is filtered in conditions to avoid moisture mixing.
