Boron Carbide Pressed

Nano-precipitation in hot-pressed silicon carbide

Heat treatments at 1300 degrees C, 1400 degrees C, 1500 degrees C, and 1600 degrees C in Ar were found to produce nanoscale precipitates in hot-pressed silicon carbide containing aluminum, boron, and carbon sintering additives (ABC-SiC).

Pressureless sintering of boron carbide phase AIP

The achieved densities are about 95% of boron carbide theoretical density.The main characteristics (composition, microstructure) of old isostatic pressed and sintered samples are compared with those of an hot‐pressed boron carbide.We give the different ways by which the carbon can act on sintering and why the starting powders behave differently.
