Carbides - Machinable by Insaco Inc.
Silicon Carbide is among the hardest of ceramics, and retains hardness and strength at elevated temperatures, which translates into among the best wear resistance also. Additionally, SiC has a high thermal conductivity, especially in the CVD (chemical vapor deposition) grade, which aids in thermal shock resistance.

High‐Strength Porous Silicon Carbide Ceramics by an …
Porous silicon carbide (SiC) ceramics were fabried by an oxidation‐bonding process in which the powder compacts are heated in air so that SiC particles are bonded to each other by oxidation‐derived SiO 2 glass. Because of the crystallization of amorphous SiO 2 glass into cristobalite during sintering, the fracture strength of oxidation‐bonded SiC ceramics can be retained to a
Corrosion characteristics of silicon carbide and silicon nitride
silicon carbide powder and allowed to react at high temperature. The resulting ceramic is generally a multiphase material that also may have a bimodal SiC grain size distribution. It is evident that silicon carbide materials that are nominally the same may have
Permeability behavior of silicon carbide‐based …
The effect of different pore formers on the microstructure, mechanical strength, porosity and pore size distribution, air, and water permeability of porous SiC ceramics were investigated. The average pore diameter, porosities, and flexural strength of the final ceramics varied in the range 3.7‐6.5 µm, 38‐50 vol. %, and 28‐38 MPa, respectively, depending on the characteristics of pore
Silicon carbide meets optical grade standards

Tuning the deformation mechanisms of boron carbide …
Boron carbide suffers from a loss of strength and toughness when subjected to high shear stresses due to amorphization. Here, we report that a small amount of Si doping (~1 atomic %) leads to a substantial decrease in stress-induced amorphization due to a noticeable change of the deformation mechanisms in boron carbide. In the undoped boron carbide, the Berkovich indentation–induced quasi
