METHOD OF FURNACE CHARGE PREPARATION FOR ZIRCONIUM BORIDE PRODUCTS Russian patent published in 2009 - IPC C04B35/58 C01B35/04

Abstract RU 2344106 C1

FIELD: chemistry.

SUBSTANCE: invention refers to ceramic product industry, specifically to methods of furnace charge preparation for boron-carbide zirconium boride products. According to method qualitative composition of the additive activating product compaction is chosen from impurities contained in crude zirconium boride, namely from ZrO₂ and/or ZrC₂ and/or B₄C. Its qualitative composition is calculated from stoichiometry of zirconium boride production from impurities and additive.

EFFECT: manufacturing of high-quality high density products not containing impurities.
