Nonferrous metal salts and oxides
Chemical product:
Antimony trioxide is a crystalline powder, white when cold, yellow when hot; it is insoluble in water and in nitric acid, somewhat soluble in diluted H2S04 and HCI; however, it becomes more soluble in these acid concentrates. A hydrochloric solution of antimony trioxide treated with H2S gives an orange precipitate which is soluble in ammonium sulphide. Also known as antimonious oxide, antimony oxide, antimony sesquioxide, and antimony snow, antimony trioxide is used in the chemical industry for the preparation of sodium antimoniate. It is also used in the glass industry and ceramic industry.
