Abstract
PURPOSE:To prevent the growth of the grains of a formed metal oxide and to easily pulverize the formed oxide with high efficiency by using a pulverization assistant at the time of producing the title metal oxide powder. CONSTITUTION:The metal powder such as Al, Mg, Si, Zr, and Ti or the Al-Si mixture and Mg-Al mixture obtained by mixing into the composition of mullite, spinel, etc., and having <=40mu mean particle diameter and the pulverization assistant such as Al(OH)3, Mg(OH)2, flour and starch are mixed in a 1/1 weight ratio to obtain raw material powder 2. The raw material powder 2 is delivered from a hopper 1, transported through a pipe 3 by a carrier gas 12 (O2), and supplied to a reaction vessel 15. Meanwhile, a combustible gas 4 is introduced into the reaction vessel 15 through a pipe 13, and ignited by a burner 8 to form a flame 9. The growth of the grains of the metal oxide is prevented by the pulverization assistant, and superfine metal oxide powder is obtained.
