▎ 摘　　要

NOVELTY - Multilayer-type heterojunction ternary boron-carbon-nitrogen functional material is synthesized by alternately stacking high-purity hexagonal boron nitride and graphite or graphene powder in mold under protective gas atmosphere, pressing into blank with pressing machine, maintaining temperature and pressure, cooling, and relieving pressure. USE - Synthesis of multilayer-type heterojunction ternary boron-carbon-nitrogen functional material (claimed). ADVANTAGE - Multilayer-type heterojunction ternary boron-carbon-nitrogen functional material has low impurity content, and synthesis is low-cost and simple. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of hexagonal boron nitride and graphite or graphene powder layered assembly. High-purity hexagonal boron nitride (1) Graphite or graphene powder (2)
