Tin(IV) oxide, also known as stannic oxide, is the inorganic compound with the formula SnO2. The mineral form of SnO2 is called cassiterite, and this is the main ore of tin. With many other names, this oxide of tin is an important material in tin chemistry. It is a colourless, diamagnetic, amphoteric solid.
Chemical formula：SnO2
Molar mass：150.708 g·mol−1
Appearance Yellowish or light grey powder
Odor：Odorless
Density：6.95 g/cm3 (20 °C)/6.85 g/cm3 (24 °C)
Melting point：1,630 °C (2,970 °F; 1,900 K)
Solubility in water：Insoluble
Application
In the pigment industry, tin dioxide is mixed with chromate, chromium trioxide, lime, vanadium pentoxide, antimony pentoxide, chlorine, etc., to produce pink, beige, yellow, gray-blue, purple-gold and other colors, as a coloring agent for ceramics and enamel. In the glass industry, used in the manufacture of opal glass and as a glazing agent. Used as fabric mordant and weight increasing agent in printing and dyeing. Tin dioxide is also used as a raw material for the production of other tin compounds, as a catalyst for the oxidation of aromatic compounds as carboxylic acids and anhydrides in organic synthesis, and in the electronics industry.
