Abstract
A ceramic composite body comprising sintered silicon carbide as major phase, dispersed boron nitride/carbon granules as minor phase, and the boron nitride/carbon granules comprise hexagonal phase boron nitride powders bonded together by glassy carbon. The composite body contains at least 3 weight percent of boron nitride, the average size of the boron nitride granules is greater than 10 micrometers, and the shape of majority of the granules is irregular. The composite body of high boron nitride loading can be further processed to improve mechanical and thermal properties by filling the porosity with glassy carbon, obtained from carbonizing glassy carbon precursor. The composite material exhibits superior thermal and tribological characteristics than monolithic silicon carbide.
