摘要：
When a powder mixture composed of Cr2O3, Al2O3, SiO2 and C was placed on a graphite powder in an alumina crucible with a lid, and the crucible was set in an electric furnace and heated to > 1350 degrees C, Cr2O3 whiskers grew at the surface of the powder mixture. The microstructure in the powder mixture, thermal analysis of the powder mixture during heating, and whisker droplet were investigated. The whiskers were found to have grown by the vapour-liquid-solid (VLS) mechanism.
