S) Reduction of the Oxide with Carbon Monoxide.—Reduction of cobalto-cobaltic oxide to the metal takes place rapidly, and is quite complete at 900° C. Between 350° and 450° C. the reaction is very interesting. At first some oxide is reduced to metallic cobalt after a time the finely divided metal decomposes the carbon monoxide, depositing solid carbon, presumably in the same way as its analogue, iron, namely ...

At about 600° C. the cobalto-cobaltic oxide is reduced to cobaltous oxide, CoO, and if this is removed from the furnace and exposed to the air it becomes incandescent in consequence of re-oxidation to the higher oxide ... [Pg.25]

Heated in ammonia to about 470° C. cobalt yields a nitride which decomposes at 600° C. Heated in nitrogen peroxide it burns with incandescence, yielding cobalto-cobaltic oxide, Cos04.8... [Pg.29]

Cobalto-cobaltic Oxide, Tri-cobalt Tetroxide, Co304, is the essential constituent of commercial oxide of cobalt. It is produced when either of the other oxides is strongly heated in air, and when cobalt nitrate is ignited. [Pg.49]

Cobalto-cobaltic oxide has been prepared in three states of hydration. The trihydrate, Co304.3H20, results on warming cobaltous hydroxide with potassium persulphate and heating the resulting product to 100° C. with dilute nitric acid.1 It is also produced as a brown precipitate on boiling a solution of roseo-cobaltic sulphate.
