Characterization, Microhardness and Dielectric Studies of Pure and Doped (Copper, Cadmium) Barium Oxalate Single Crystals Grown in Silica Gel

Abstract

Single crystals of pure barium oxalate, copper doped barium oxalate and cadmium doped barium oxalate crystals are grown by gel method. The double diffusion (U-tube) method is adopted for growing crystals. The crystals are of few mm in size. 5-7 d taken for gel set and 45-60 d taken for complete growth of the crystals. The X-ray diffraction patterns of the samples revealed their crystalline nature. Thermo gravimetric analysis data supported the release of lattice H₂O, CO, and CO₂. The FTIR spectrum of the crystals showed the presence of water molecules and carboxylic acid. The characteristics are slightly different due to the doping with impurities. The microhardness and dielectric studies of grown crystals were also carried out.
