Nickel (III) oxide is a binary inorganic compound of nickel metal and oxygen with the formula Ni ₂ O ₃ , a dark gray powder that does not dissolve in water, forms hydrates.

Getting

Careful heating of nickel nitrate or chlorate .

Physical Properties

Nickel (III) oxide forms dark gray crystals of cubic syngony , space group F m3m , cell parameters a = 0.41798 nm, Z = 4.

Forms hydrates of non-stoichiometric composition Ni ₂ O ₃ • x H ₂ O, where x < 2.

Chemical Properties

It decomposes on heating to nickel oxide (II, III) :

{\mathsf {6Ni_{2}O_{3}\ {\xrightarrow {600^{o}C}}\ 4Ni_{3}O_{4}+O_{2}}}

{\ displaystyle {\ mathsf {6Ni_ {2} O_ {3} \ {\ xrightarrow {600 ^ {o} C}} \ 4Ni_ {3} O_ {4} + O_ {2}}}}

{\mathsf {6Ni_{2}O_{3}\ {\xrightarrow {600^{o}C}}\ 4Ni_{3}O_{4}+O_{2}}}

Application

Production of anodes of alkaline batteries .
