Densification of 4 B C during sintering can be aided by removing the native 23 BO (condensed) layer present on the starting 4 B C powder. B2O3 can be removed by adding excess C and holding the powder compact at an intermediate temperature below the n

Carbon, which is often used as an additive to silicon carbide powder, is thought to facilitate densification during sintering by aiding the removal of the native SiO2 layer, which is present on the starting SiC powder. The mechanism is the reduction
