Investigation on the Aqueous Solution for Growth of Bimetallic Thiocyanate Complex Crystal Materials

The stability of cadmium mercury thiocyanate (CMTC) crystal growth solution was mainly discussed. The effects of temperature, pH value, time and KCl concentration on CMTC crystal growth were investigated. The effects of pH value and KCl concentration on crystallization habit of CMTC were also studied. The results show that when pH value ranges from 2.5 to 3.8, the solution is relatively stable, under the condition of pH <= 2.0 or pH => 4.0, the solution has poor stability and some powder appears. The solution becomes unstable at high temperatures. When the concentration of KCl is more than 27% there has not generated CMTC crystal in the solution, a new kind of material produced from solution. The pH value and KCl concentration affect crystalline morphology of CMTC crystal.

Keywords: nonlinear optical material, micro-crystallization, solubility curve, stability
