Beschreibung
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.
Chemische Eigenschaften
solid
Verwenden
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.
Hazard
Confirmed carcinogen.
Industrielle Verwendung
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.
Sicherheitsprofil
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.
