What's the difference of Recrystallized Silicon Carbide(RSiC) and Silicon Nitride Bonded Silicon Carbide(NSiC)?

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.

Silicon Nitride Bonded Silicon Carbide (NBSiC) is designed for exceptional wear resistance and can be formed into very intricate and precise shapes with the Blasch process. It has desirable refractory and chemical properties, and can also exhibit exceptional wear and thermal shock resistance.
