Abstract

Mixed crystals of cadmium oxalate are grown in silica gel by varying gel parameters, concentration of reactants and gel aging. The optimum conditions for the crystal growth are established. Mixed crystals of cadmium oxalate are grown by mixing with different cations Ba+2, Ca+2, Mn+2, Sr+2, Co+2, Ni+2, Cr+2, Zn+2 with Cd+2. These cations have changed the morphology of original cadmium oxalate crystals, results the growth of new mixed oxalate crystals. The mixed cadmium oxalate crystals were characterized using energy dispersive X-ray spectroscopy (EDAX) and thermo-gravimetric analysis. Optical properties of barium mixed cadmium oxalate crystal are discussed. Depending on their properties, the oxalate mixed crystals will be used in the development of special electronic and semi conducting devices.
