Abstract:

Commercial CuCl was found to be unsatisfactory for crystal growth. Purification was achieved both by chemical and by zone-melting techniques. CuCl ingots pulled from pure melts were found to be strained, highly twinned, and polycrystalline because of the wurtzite-to-zincblende phase transition. This phase transition was avoided by addition of from 5 to 15 KCl to the melt. Difficulty was encountered with evaporation of the CuCl and with strings of small inclusions in the flux-grown crystals. Mechanical processes produced no twins at room temperature but did result in residual strain. Author
