Also known as
NICKEL OXIDE BLACK LR
Black Nickel Oxide (Ni2O3) Used in the manufacture of exhaust catalysts, Black Nickel Oxide is a non-stoichiometric chemical that contains approximately 77% nickel. It shows greater chemical reactivity than Green Nickel Oxide, particularly in acidic media.
Note
A powerful and refractory colorant that produces greys, blues, and yellows. It is more concentrated than nickel carbonate and as little as .02% gives a noticeable tint. Normal additions are 2-5%.
Typical grades are 75-77% nickel metal with trace elements (0.0001-0.01%) of cobalt, iron, copper, zinc, manganese, magnesium, calcium, sodium and sulfur and chloride volatiles. Particle sizes can be very fine, down to 5 microns (below 325 mesh). It is insoluble in water and soluble in acids.
NiO has a variety of specialized applications and generally, applications distinguish between "chemical grade", which is relatively pure material for specialty applications, and "metallurgical grade", which is mainly used for the production of alloys. It is used in the ceramic industry to make frits, ferrites, and porcelain glazes. The sintered oxide is used to produce nickel steel alloys.
