Title:
PRODUCTION OF SPHERICAL POWDER AND SPHERICAL POWDER PRODUCED THEREBY
Document Type and Number:
Japanese Patent JP3276330
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the method for producing spherical powder by an atomizing thermal decomposing method by which the spherical powder to be produced is hard to be formed into hollow bodies and porous bodies, and to provide the spherical powder produce by the method.
SOLUTION: In this method for producing spherical powder by an stomizing thermal decomposing method using a soln. contg. metallic elements (e.g. an aq. soln. of nickel nitrate) as a starting raw material, a soln. contg. one or more kinds of metallic elements is blended with an additive capable of coordinate linkage with the metallic ions (e.g. ammonia) to form a complex having stability under the condition of a room temp. and decomposed under the condition of heating to form precipitates (e.g. alkaline Ni(NH3)6(NO3)2], and the soln. cong. this complex is used as the starting raw material.
