Nickel oxide

Описание

Nickel oxide (Ni2O3) is an important metal oxide used as a plating agent, surface treatment agent, and photocatalyst. Ni2O3 is also used as an electrode material in the manufacture of fuel cells and as a catalytic material in the production of electrolytic cells.

Химические свойства

solid

Использование

Nickel oxide (NiO) is produced from nickel minerals to form nickel oxide when heated to 400°C, which is then reduced at a temperature of 600°C, resulting in the formation of nickel oxide. It is used as electrodes in fuel cells.

Опасность

Confirmed carcinogen.

Промышленное использование

Nickel produces a bluish-violet in potash glasses and a violet tending toward brown in soda glasses. Nickel rates as one of the more powerful colorants, since 1 part in 50,000 produces a recognizable tint. Nickel oxide is sometimes used to decolorize potash glass. Nickel oxide and nickel silicate have an advantage over manganese dioxide for decolorizing purposes in that they are not as sensitive in changing oxidizing and reducing environments.

Профиль безопасности

Confirmed human carcinogen. Poison by subcutaneous route. Mutation data reported. Hazardous reaction with hydrogen peroxide. Presence of the oxide increases the sensitivity of nitroalkanes (e.g., nitromethane, nitroethane, 1 -nitropropane) to heat. See also NICKEL COMPOUNDS and PEROXIDES.
