FIELD: process engineering.
SUBSTANCE: invention relates to production of powders for microwave hardware and micro optics. Proposed method comprises preparation of water solutions of yttrium (III) and iron (III) salts. First, precipitator agent, a highly-basic gel anionites hydroxide AB-17-8 is brought in contact with the solution of yttrium (II) salt at the room temperature for 60 minutes. Then, the solution of iron (III) salts id added. Precursor product is settled from obtained solution and separated therefrom, dried and annealed at, at least 700°C.
EFFECT: nano-sized iron-yttrium garnet powder produced without use of aggressive media, high temperature and pressure.
