Lead IV oxide. It is also attacked by concentrated alkali to yield salts of CrOH 6 3.
After the reaction mass has cooled it is broken up and the.
Chromium iii oxide. ChromiumIII oxide is amphoteric. Although insoluble in water it reacts with acid to produce salts of hydrated chromium ions such as CrH 2 O 6 3. It is also attacked by concentrated alkali to yield salts of CrOH 6 3.
When heated with finely divided carbon or aluminium it is reduced to chromium metal. Cr 2 O 3 2 Al 2 Cr Al 2 O 3. Unlike the classic thermite reaction.
ChromiumIII oxide Cr 2 O 3. Chromium dioxide chromiumIV oxide CrO 2 which includes the hypothetical compound chromiumII chromate. Chromium trioxide chromiumVI oxide CrO 3.

The industrial production of chromiumIII oxide involves the reduction of solid sodium dichromate generally with sulfur. The finely divided components are thoroughly mixed fed into a brick-lined furnace and brought to dark-red heat. The reaction proceeds exothermically.
After the reaction mass has cooled it is broken up and the. ChromiumIII oxide sputtering target 762mm 30in dia x 635mm 0250in thick 998 metals basis PubChem. 3 Chemical and Physical Properties.
