COMPLEX METAL OXIDE POWDER AND METHOD FOR THE PRODUCTION OF THE SAME |
摘要 |
A complex metal oxide powder having at least two metal elements, which contains polyhedral particles each having at least 6 planes, a number average particle size of from 0.1 to 500 .mu.m, and a D90/D10 ratio of 10 or less in which D10 and D90 are particle sizes at 10 % and 90 % accumulation, respectively from the smallest particle size side in a cumulative particle size curve of the particles, and an yttrium-aluminum garnet powder containing polyhedral particles each having at least 6 planes, and a number average particle size of 20 to 500 .mu.m. These complex metal oxides contain less agglomerated particles, and have a narrow particle size distribution and a uniform particle shape.
