pure silicon carbide sintered

Brevier Technical Ceramics - Keramverband

Recrystallized silicon carbide (RSIC) is a pure silicon carbide material with approximately 11 to 15 % open porosity. This material is sintered at very high temperatures from 2,300 to 2,500° C, at which a mixture of extremely fine and coarse grains is converted to a compact SiC matrix without shrinkage.

Porous Silicon Carbide: Preliminary Results

Abstract – A ultra pure silicon carbide powder was used to sinter a porous silicon carbide. The purifiion was done via HF acid and the material was sintered at 1925 ºC. The final density was 67% and the strength was 96 MPa. The porous medium had a size

CARBIDE CERAMICS

Nitride Bonded Silicon Carbide ceramics are produced from a mixture of silicon carbide and silicon powders, which is sintered first in Nitrogen atmosphere and then in oxidizing atmosphere. The resulting material has small pores with open porosity up to 5%.
