ABSTRACT:
Silicon carbide material retains the hardness, wear and heat resistance properties and can be rendered conductive by the incorporation of an element of the same valence as silicon and carbon in quantities in the range of 0.01% to 0.03%. Germanium in this range in SiC is conductive. The material is very hard, is electrically conductive in the 2.times.10.sup.-4 ohm cm range and is useful in highly corrosive and abrasive applications.
