| 英文摘要 | We report the synthesis of boron carbide powder via the reaction of hexagonal boron nitride with carbon black. the reaction between hexagonal boron nitride and carbon black completed at 1900 degrees c for 5 h in vacuum. the particle sizes of the synthesized boron carbide powder were about 100 nm from transmission electron microscopy. the possible reaction mechanism was that hexagonal boron nitride decomposed into elemental boron and nitrogen even when there was no carbon at a relatively low rate, and introduction of carbon into hexagonal boron nitride powder facilitated the decomposition process; the boron from the decomposition of boron nitride reacted with carbon to form boron carbide.
