Tin dioxide

Tin (IV) oxide, also known by the systematic name stannic oxide in the older notation, is the inorganic compound with the formula SnO₂. It is not named tin dioxide because Tin is a Type II Metal, and so is named Tin (IV) Oxide by nomenclature. The mineral form of SnO₂ is called cassiterite, and this is the main ore of tin. With many other names (see infobox), this oxide of tin is the most important raw material in tin chemistry. This colourless, diamagnetic solid is amphoteric.
