METHOD OF PREPARING BORON CARBIDE, INTERCALATED COMPOUND OF GRAPHITE OXIDE WITH DODECAHYDRO-CLOSO-DODECABORATE ACID, AND METHOD OF SYNTHESIS OF THIS COMPOUND

摘要

FIELD: inorganic syntheses. SUBSTANCE: invention relates to boron carbide useful as neutron absorbent in nuclear engineering and as abrasive for polishing, and, when sintered in the form of cutters, for working hard materials. Preparation is based on using new intercalated compound - compound of graphite oxide with dodecahydro-closo-dodecaborate acid which is thermally decomposed in oxygen atmosphere. EFFECT: increased purity of boron carbide. 4 cl, 5 ex
