Abstract

Commercial silicon carbide (SiC) powders are composed of a wide range of particle sizes, typically 0.5 to 15um depending on the powder. It was shown that by eliminating large particles and hard agglomerates greater than 2um improved microstructural uniformity in hot pressed parts could be achieved. The effect of carbon over-additions ranging from 0.25 to 5 % on microstructural uniformity was also examined. It was found that for over-additions of carbon exceed 1 % the Knoop hardness was shown to decrease by as much as 20% compared with conventionally prepared, dense SiC. The effect of increased carbon percentages on microstructure and hardness was shown.
