  • Tin (II) Oxide (Stannous Oxide) / Tin (IV) Oxide (Stannic Oxide) Designations:

Chemical Name: Tin oxide

Chemical Formula Options:

a) Tin(II) oxide / Stannous oxide= SnO

b) Tin(IV) oxide / Tin dioxide / Stannic oxide= SnO2

  • Tin (II) Oxide (Stannous Oxide) / Tin (IV) Oxide (Stannic Oxide) General Description:

a) A powder, off-white in color, produced thermally from high grade tin metal

b) Tin(II) oxide (stannous oxide) with the formula SnO is a compound of tin and oxygen where tin has the oxidation state of +2. There are two forms, a stable blue-black form and a metastable red form.

c) Tin 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 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.
