Silicon carbide - Wikipedia

Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive.Grains of silicon carbide can be bonded together by sintering to form very hard ceramics that are widely used in appliions

Microhardness anisotropy of silicon carbide

to control hardness anisotropy and to estimate the yield stress of SiC at room temperature. Some data on the Knoop hardness anisotropy of silicon carbide has been published by Shaffer [15] and this was rationalized in terms of one possible slip system ({1 i-0 0}(1 1 20)) by Brookes et al. [1 ]. However, these data, which are repro-
