Tin(II) oxide

Synonyms

Tin monoxide; Tin oxide (SnO); Stannous oxide; [ChemIDplus] Tin protoxide; [Merck Index] Tin (II) oxide black; [ACGIH] Tin(2+) oxide; [CAMEO]

Category

Metals, Inorganic Compounds

Description

Brownish-black solid; [Merck Index] Bluish-black odorless powder; [Alfa Aesar MSDS]

Sources/Uses

Tin oxides are used in solders, protective coatings, and alloys; [ACGIH] Used as a reducing agent and to make stannous salts; [Merck Index] Used to make gold-tin and copper-tin ruby glass; [INCHEM CICADS] "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." [Wikipedia]

Comments

May cause mechanical respiratory tract irritation; Stannosis is a benign pneumoconiosis caused by inhalation of tin dust or fume. [ICSC] Slowly oxidized by air forming tin(IV) oxide; [CAMEO] May cause irritation; Harmful by ingestion; [Alfa Aesar MSDS] See "Tin and inorganic compounds." See "Tin(IV) oxide."
