Abstract

PURPOSE:To prepare fine skin-colored zinc oxide fine powder having the transparency and slipperiness, by filtering and collecting a precipitate formed in dropping a solution of a zinc salt into a solution containing oxalic acid radicals, and placing the resultant precipitate in a gaseous atmosphere containing ammonia. CONSTITUTION:A solution of a zinc salt consisting of zinc chloride, zinc, nitrate or zinc sulfate is dropped into a solution, containing oxalic acid radicals, and consisting of oxalic acid, an alkali oxalate or ammonium oxalate, and the resultant precipitate is filtered, collected and then placed in a gaseous atmosphere containing 5vol% or more ammonia at 350-550 deg.C for 0.5-3hr. The solution contains 20-200g/l zinc ions, and solution containing the oxalic acid radicals in a concentration of 30-300g/l. The volume ratio of the solutions between the zinc and the oxalic acid radicals is about (1:4)-(4:1). The resultant precipitate has a particle diameter of about <=0.5mum, and the particle diameter of the zinc oxide can be adjusted to about <=100nm.
