SnO, Tin Oxide, Tin(II)Oxide, Tin Monoxide, Tin Protoxide, Stannous Monoxide, Monoxide Protoxide, CAS 21651-19-4, EINECS 244-499-5
Product Name: Stannous Oxide.
Chemical formula: SnO.
Molecular weight: 134.71.
CAS number: 21651-19-4.
EINECS number: 244-499-5.
Purity: 99.9%.
Particle size: millimeter level,micrometer level, nanometer level（customized production according to customer requirements）.
Appearance: Blue black powder.
Characteristics: Blue black metal crystalline powder. Odorless or slightly with a hydrochloric acid odor. Insoluble in water and ethanol, soluble in acid and concentrated NaOH and KOH solutions. Avoid contact with strong oxidants and acids. Stable at room temperature and pressure. At 1080 ℃, it decomposes, and when heated to 220 ℃ in air, tin oxide is generated. Neutral aqueous solutions are easily hydrolyzed to form precipitates, soluble in concentrated hydrochloric acid and concentrated caustic soda, and have strong reducibility.
Application:
Used for the preparation of catalysts, reducing agents, glass industry, stannous salts, and in electroplating for the formulation of stannous fluoroborate and other soluble stannous salts.
