Abstract

PURPOSE:To obtain platy nickel hydroxide having a uniform shape and useful as starting material for electronic ceramics, a filler, etc., as fine particles by adding alkali to an aq. soln. of an Ni salt and aging the soln. adjusted to a specified pH at a specified temp. CONSTITUTION:Alkali is added to an aq. soln. of an Ni salt such as nickel nitrate. The pref. concn. of the Ni salt is 0.01-5mol/l. The soln. adjusted to pH >=10 is aged at 10-300 deg.C to obtain hexagonal platy nickel hydroxide of 0.01-0.2mum particle size. The aging time is several to several ten days in the case of the low temp. and several to several ten hr in the case of the high temp.
