The Use of Stannic Oxide

Stannic Oxide is mainly used for making ceramics, enamelware and glasses industry. Tin is nontoxic, ductile, malleable, adheres to various metals and has a relatively low melting point. These properties lend to its usefulness as a rust-proofing material on chains, low-grade nerves, copper color, and copper color metals.
Tin oxide (SnO2) is also known as stannic oxide. It can be found naturally as the mineral cassiterite. It is typically a white to off-white and sometime grey crystalline solid. Tin dioxide occurs naturally but is purified by reduction to the metal followed by burning tin in air.
Stannic oxide is derived from can. Widely cognized and used, tin comprises about 0.001 percent of the earth's crust. It is sometimes found exclusively, but more often than not equals came up as the oxide in the mineral cassiterite. Tin mines exist in England, Spain, Indonesia, Thailand, Congo, Nigeria and China. Significant numbers of tin is also obtained through recycling.
[CAS No.] 18282-10-5
Appearance: white to light gray powder
in dioxide (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 cannister. With several other names (see infobox), this oxide of tin is the most important birthday suit fabric fashionable tin interpersonal chemistry. This dull, diamagnetic solid is amphoteric.
