Tin Oxide Granules (SnO2 Granules)

Physical and chemical properties

Form: white tetragonal crystal

Density: 6.95g/cm³

Melting point: 1630 degrees Celsius.

Properties: Insoluble in water, alcohol, dilute acid and lye, soluble in concentrated sulfuric acid, co-dissolving with alkali to form stannate.

Preparation method: It can be obtained by burning tin in the air or by heating and decomposing Sn(OH)₄ (the natural product is cassiterite).

Others: also known as tin oxide, white or yellow (yellow generally contains Cl-), tetragonal, hexagonal or orthorhombic crystal, sublimation at 1800 ~ 1900 ℃. Insoluble in water, alcohol, dilute acid and lye.
