Tin(II) oxide (SnO)-Crystal introduce:


Tin(II) oxide (stannous oxide) is a compound with the formula SnO. It is composed 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.

Chemical formula:SnO

Molar mass:134.709 g/mol

Appearance:black or red powder when anhydrous, white when hydrated

Density:6.45 g/cm3

Melting point:1,080 °C (1,980 °F; 1,350 K)

Solubility in water:insoluble

Magnetic susceptibility (χ):−19.0·10−6 cm3/mol

Crystal structure:tetragonal


The dominant use of stannous oxide is as a precursor in manufacturing of other, typically trivalent, tin compounds or salts. Stannous oxide may also be employed as a reducing agent and in the creation of ruby glass. It has a minor use as an esterification catalyst.

Cerium(III) oxide in ceramic form, together with Tin(II) oxide (SnO) is used for illumination with UV light.
