Abstract:
Various crystal growing techniques were investigated as possible means of producing large size single crystals of synthetic mica fluorphlogopite type on a commercially feasible basis. Methods included crystal pulling, zone melting, and growth from solution. Most favorable results were obtained from a progressive internal resistance melting using zone melting principles, however, no method was found for delamination of the crystal books. Crystal pulling techniques were unsatisfactory. Zone melting, using inductive heating, produced crystals with good orientation, but crystal size was small. Progressive melting, using the internal resistance method of heating produced the largest crystals. Relatively large percentages of such crystals were obtained within a melt. These crystals were larger than those produced by standard production techniques. Crystals of synthetic mica can be grown from a solution using glass as a solvent. Author
