Compacts and composites were sintered under high pressure (2 GPa - 10 GPa) and high temperature (1400 - 2300 ? C) conditions. The compacts were sintered using nano-SiC powder, micron-diamond powder, and nano-diamond powder. Composites were sintered using the liquid infiltration method from nano-silicon powder and nano or micron diamond powder.
Boron Carbide (B4C) - Properties and Information about
Feb 09, 2001· Background. Boron Carbide (B 4 C) is one of the hardest materials known, ranking third behind diamond and cubic boron nitride. It is the hardest material produced in tonnage quantities. Originally discovered in mid 19 th century as a by-product in the production of metal borides, boron carbide was only studied in detail since 1930.. Boron carbide powder (see figure 1) is mainly …
