Effects of 20-40 vol.% SiCp additions on microstructure and hardness of aluminum composites have been investigated in this research. The composites were produced via powder injection molding at 170 C followed by solvent debinding and sintering at 700-820 C.
Silicon carbide powder is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. And is also used as a support and shelving material in high temperature kilns such as for firing ceramics, glass fusing, or
Silicon carbide probably has the best resistance to corrosion in acids and alkalis of all advanced ceramic materials. It also has extreme hardness and high thermal conductivity and outstanding mechanical properties up to 1400 C. Silicon carbide ceramics have
THERMASIC – SILICON CARBIDE BASED POWDER FOR THERMAL SPRAY Seram Coatings´ product ThermaSiC enables SiC (Silicon Carbide) to be applied as a coating by thermal spraying for the first time. ThermaSiC provides superior coating performance in corrosive and abrasive environments as well as at high temperatures (up to 1500° C in air and 2400° C in inert atmosphere).

Boron Carbide Grinding Powders In terms of hardness, Boron carbide (B 4 C) with a Mohs hardness of 9.5 is third only to diamond and so makes an excellent lower cost alternative to diamond for the precision grinding, lapping and polishing of most hard materials.
For this study, 500 g Vickers indentation was used as a way to induce amorphization in boron carbide and interrogate hardness. The larger area from the Vickers indents allowed amorphization to be probed in greater detail compared to nanoindentation.
Silicon Carbide and Boron Carbide 143 Vickers Hardness (GPa): 27.4-34.3 Modulus of Elasticity (GPa): 290-450 Shear Modulus (GPa): 165-200 Bulk Modulus (GPa): 190-250 Poisson’s Ratio: 0.18 Flexural Strength (MPa): 323-430 Compressive
