Studies on impurity incorporation in cadmium oxalate crystals grown by gel method

Aspects of gel growth of cadmium oxalate single crystals doped with monovalent (Li+, Na+, K+ and NH4+) and divalent (Ca2+, Co2+, Ni2+ and Zn2+) cation impurities are discussed. The growth experiments were carried out by single diffusion method. In this paper the effect of composition of the supernatant solution is considered. Rigorous characterization involves determination of composition of cations by employing atomic absorption spectrophotometer and of anions by titration method. The Pauling radius, hydration energy and distribution coefficient of the cations are tabulated and the results are described and discussed.
