Silicon monosulfide is an inorganic chemical compound of silicon from the group of sulfides .

Occurrence

Silicon monosulfide has been detected in interstellar space.

Extraction and presentation

Silicon monosulfide can be obtained by reacting silicon with 1.1 times the stoichiometric amount of sulfur at 650 to 700 ° C, although silicon disulfide is also formed to a large extent.

Alternatively, it may also by comproportionation of silicon sulfide and silicon at 850 ° C in monomeric form or by reaction of silicon with carbon disulfide at 1000 ° C or with iron (II) sulfide obtained at 1200 ° C.

properties

Silicon monosulphide is a yellow, polymeric, amorphous, metastable substance that decomposes with the slightest trace of moisture. It can be obtained in two forms, the fibrous form being more reactive than the glassy. The former sometimes disproportionates spontaneously with glowing and lightening. Above about 650 ° C the rate of disproportionation to silicon disulfide and silicon increases markedly.
