SILICON DISULFIDE Usage And Synthesis

Chemical Properties

sublimed cotton-like fibrous clumps with 99.9% purity; white, fibrous mass or needles; rhomb, a=0.560 nm, b=0.553 nm, c=0.975 nm; decomposes in moist air to evolve H2S; burns if ignited by a flame [MER06] [CIC73] [CER91]

Chemical Properties

silicon disulfide, SiS2, white crystals, formed by heating amorphous silicon and sulfur, and then subliming, reactive with water.
