Stannic oxide Chemical Properties,Uses,Production
Chemical Properties
white or off-white powder
Physical properties
White or grayish powder; tetragonal crystals; density 6.85 g/cm3; refractive index 2.006; Mohs hardness 6.5; melts at 1,630°C; insoluble in water; soluble in hot concentrated alkalies.
Uses
Stannic oxide (SnO2) is a whitish powder used as a ceramic glaze and polishing agent.
Preparation
Tin(II) oxide is prepared by heating tin(II) hydroxide. The latter is obtained as a white precipitate by reacting Sn2+ ions with hydroxide ions: Sn2+(aq) + 2OHˉ(aq) → Sn(OH)2 (s) Sn(OH)2 ?→ ?? SnO(s) + H2O(g).
General Description
White or off-white crystalline solid or powder. Mp 1127°C, Sublimes: 1800-1900°C, density: 6.95 g cm-3. 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.
Reactivity Profile
TIN(IV) OXIDE is non-flammable and non-combustible. Reacts vigorously with strong reducing agents. Incompatible with chlorine trifluoride.
Purification Methods
Reflux it repeatedly with fresh HCl until the acid shows no tinge of yellow. The oxide is then dried at 110o.
