▎ 摘　　要

NOVELTY - Production of silicon carbide material (12) involves reacting a carbon material (4) and a silicon-containing gas (2) in a reaction chamber at an elevated temperature of up to 2400degrees Celsius and a pressure of about atmosphere, and maintaining a partial pressure of oxygen in the reaction chamber of 1.01x102 Pa or less to produce silicon carbide nanoparticles. USE - Manufacture of silicon carbide material such as ~a-silicon carbide for forming ceramic matrix composite, metal matrix composite and polymer matrix composite for industrial areas, military areas, nuclear areas, electrical areas, and aerospace areas. ADVANTAGE - The method is simple and inexpensive, and enables manufacture of silicon carbide material with excellent thermal efficiency, thermal conductivity, and mechanical stability. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic illustration of reaction chamber.
