Effect of addition of tartaric acid on synthesis of boron carbide powder from condensed boric acid-glycerin product

Abstract

Crystalline boron carbide (B₄C) powder was synthesized from the precursor obtained by pyrolysis of boric acid-glycerin condensed product with tartaric acid addition in air. The prepared precursor powder had a bicontinuous carbon/boron oxide (B₂O₃) network structure with tartaric acid addition which had more dispersed microstructure of carbon and B₂O₃. The factor of shortening the synthesis time was development of the precursor structure.
