General Description
White or off-white crystalline solid or powder. mp: 1127°C, Sublimes: 1800-1900°C, density: 6.95 g/cm3 Insoluble in water. Soluble in concentrated sulfuric acid, hydrochloric acid. Occurs in nature as the mineral cassiterite. Used as a catalyst, in putty, as a polishing powder for steel and glass, in ceramic glazes and colors. "Flowers of tin" refers to the material collected as the result of condensation after sublimation.
