tin iv oxide is a white or off-white crystalline solid, or powder. It has a melting point of 1127degC, a sublimed temperature of 1800-1900degC and a density of 6.95 g/cm3. The mineral form of this compound is cassiterite (SnO2) and it is often called flowers of tin. It is used in ceramic glazes and colors, putty, perfume preparations, textiles, polishing powder for steel, and the manufacture of special glasses.
In the United States, tin iv oxide is considered to be safe at concentrations up to 0.4% in rinse-off products and up to 1.3% in leave-on products. The Cosmetic Ingredient Review Expert Panel has concluded that tin iv oxide is not likely to be harmful when it is present at these concentrations in cosmetic products.
Chemical Formula: SnO2
Physical and Chemical Properties
Tin oxide is a basic anhydride and reacts vigorously with strong reducing agents in redox reactions. The crystalline form is stable and has been used in the production of ceramics. It is also useful in advanced electronic applications and for fuel cells where it exhibits ionic conductivity.
American Elements produces tin oxide in pellets, pieces, sputtering targets, tablets and nanopowders. It is usually immediately available in most volumes.
