Digital images of, (a) silicon carbide powder, (b) exfoliated carbon fibers, (c) ball milled mixture of carbon fibers and silicon carbide powder. The main motive for exfoliating the chopped fiber tows prior to ball milling was to further reduce the length of the CFs at a faster rate than conventional methods, and also to aid in the uniform dispersion of CFs in SiC powder.

Effect of Submicron Silicon Carbide Powder Addition on the Processing and Strength of Reaction-Sintered Mullite-Silicon Carbide Composites Article in Journal- Ceramic Society Japan 117(1364):421
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.
Silicon carbide is mostly used for its hardness and strength, though its coined ceramic and semiconductor properties make SiC excellent in the manufacturing of fast, high-voltage, and high-temperature devices [1].
Recently, Beijing High-Pressure Scientific Research Center obtained a new idea for high strength metal processing: high-pressure fine grain strengthening Generally, the smaller the grain, the higher its strength. However, scientists have calculated throu
