INVESTIGATION OF CRYSTAL GROWTH PROCESSES
Abstract
A method for purification of KC1 by anion and cation exchange was developed. The crystalline product of the purification process and single crystals grown from this product were evaluated. This investigation shows that the method produces crystals superior to those currently available commercially. Optical data indicate the OH(-), Br(-), and I(-) concentration was reduced. Emission spectroscopy indicates the Na() con tent was significantly reduced. Electrical conductivity measurements indicate that the divalent-ion concentration is comparable to that of 10-pass zone-refined material if compensation not occur in either case. This work was reported at the 1962 International Color Symposium in Stuttgart, Germany. An attempt was made to grow crystals from an H2S solvent at high temperatures and pressures. To date these results have not met with success, but measurements of solubility show that it is a possible method for growing CdS and ZnS.
