Silicon Carbide: The Return of an Old Friend

The strength of a silicon carbide ceramic component is generally determined by pre-existing flaws introduced into the material during processing. The type, size, shape, and loion of the flaws vary considerably and, consequently, so does the strength. Silicon carbide ceramics made by different techniques also have quite distinct mechanical properties. For example, sintered silicon carbide
