METHOD OF PREPARING OF POWDER-LIKE OXIDE COMPOUNDS Russian patent published in 1995 - IPC

Abstract RU 2031885 C1

FIELD: radioelectronic engineering. SUBSTANCE: for preparing of powder-like oxide compounds of composition Ba(Mg1/3Э2/3)O3, where Э - Ta, Nb solution of tantalum or niobium alkoxide in the form of their butylate or methylcellosolvate were prepared. The latters are in the organic solvent - methylcellosolve or butyl alcohol. Then magnesium is added in the form of chips, and hydrolysis is carried out using barium hydroxide and water at mixture heating following by separation of precipitate and its drying under vacuum at 80-120 C. EFFECT: improved method of product preparing. 1 tbl
