Abstract : Microhardness measurements show that boron additions do not increase the microhardness of single crystal silicon carbide. Etching studies, to remove surface defects leading to low strengths of single crystals, have been initiated to find a means of improving the overall strength of silicon carbide crystals. Earlier data are being evaluated statistically by means of a computer program. (Author)
