Synthesis of LaBe-ZrBz powder mixture by borothermal reduction of La(OHh and ZrO(OH)2 co-precipitated in a boron suspension
https://doi.org/10.17073/1683-4518-2019-8-38-43
Abstract
The eutectic composition powder mixture was synthesized in the LaB6-ZrB2 system by borothermal reduction of a mixture of La(OH)3 and ZrO(OH)2 in vacuum at isothermal holding temperatures from 1200 to 1600 °С. A mixture of hydroxides was obtained by co-precipitation from aqueous solutions of lanthanum and zirconyl nitrates in a suspension of amorphous boron. The effect of boron excess on the phase and elemental composition of a mixture of borides was studied. The dependence of the dispersion of the obtained powders on the synthesis temperature was established. Ill. 5. Ref. 45.
