| Research Abstract |
Spherical boron carbide and tungsten carbide particles were obtained by laser irradiation of boron and tungsten particles dispersed in organic solvents. Carbide spherical particles of boron and silicon were also obtained by laser irradiation of dispersed angular carbide particles in solvent. The technique using a laser irradiation in liquid is available for spherical particle fabrication of materials with high hardness and high melting point, which is generally difficult by conventional chemical method and mechanical milling.
