Microwave synthesis of nanosized particles of a complex oxide system with a garnet structure

Abstract

The possibility of applying the method of microwave synthesis for the fabrication of nanosized particles of complex oxides has been demonstrated. The effect of fabrication conditions on the size of nanoparticles with a garnet structure has been established on the example of the Gd–Ga–Al–O system. The concentration of the organic solvent for obtaining particles of an average size of 50 nm has been determined experimentally. The phase composition of thermally treated samples has been investigated. The optimal conditions of producing nanosized powders of garnets, Gd₃(Ga,Al)₅O₁₂, have been determined.
