Used as an electrolyte in nickel plating solutions, an oxygen donor in auto emission catalysts, forms nickel molybdate, anodizing aluminum, conductive nickel zinc ferrites, in glass frit for porcelain enamel, thermistors, varistors, cermets, and resistance heating elements.
NiO has a variety of specialized applications and generally applications distinguish between “chemical”, 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. Charles Édouard Guillaume won the 1920 Nobel Prize in Physics for his work on nickel steel alloys which he called invar and elinvar.
