摘要

We have developed high purity CVD-SiC powder by crushing the CVD free standing deposit mechanically. The powder has the diameter range of 200 to 1, 200 micro-meters and has sub ppm level impurity, thus enabling us to adopt it as the source material for making single crystal SiC by sublimation method. Characteristics of the powder are discussed in comparison with the powder by conventional Acheson's method.
