Three dislocation etchants, , , and , and two chemical polishes, and have been investigated as to their effective temperature and orientation ranges on sapphire. In addition the etchants are compared for effectiveness of dislocation pitting. It is found that the best pitting is obtained with on the plane, and on the (0001) plane.
