摘要
FIELD: inorganic compounds production. SUBSTANCE: complex metal oxide powder is provided having at least two metal elements and containing polyhedral particles, each having at least 6 planes and whose number-average particle size ranges from 0.1 to 500 mm and D90/D10 ratio is equal to 10 or less (D10 and D90 are particle sizes at 10 and 90% accumulation, respectively going from smallest size on summary particle-size curve). Also provided is yttrium-aluminum garnet powder containing polyhedral particles, each having at least 6 planes and whose number-average particle size ranges from 20 to 500 mm. These complex metal oxides contain less agglomerated particles and are characterized by narrow size distribution and uniformly shaped particles. EFFECT: improved homogeneity. 46 cl, 3 tbl, 21 ex
