Mainly deals with studies made on the growth of barium, strontium and cadmium oxalate single crystals in gel medium and on the characterization of the grown crystals. The entire work is divided into three parts. The first part contains three chapters. Introductory, Existing information and Experimental techniques. The second part of the work is devoted to growth kinetics and characterization of barium, strontium, and cadmium oxalates. It contains 4-9 chapters and the third part contains chapter 10 describes conclusions derived from different experimental measurements carried out during the present investigations.
