Silicon Carbide: The Return of an Old Friend

The term “silicon carbide” is commonly used to describe a range of materials that are in fact quite distinct. Mechanical engineers may use it to describe ceramics which are fabried from relatively impure SiC crystallites bonded together with various binders under temperature and/or pressure, while electrical engineers may use the term to describe high purity single crystal wafers of SiC.
