Microhardness Variation of Cobalt Doped Cadmium Oxalate Single Crystals Due to Dopant's Concentration

M. Abdul Salim and R. Raveendran

Pure and cobalt doped cadmium oxalate single crystals were grown by gel technique. These were characterized and undergone ICPAES and microhardness measurements. Characteristics such as powder XRD and FTIR are taken. The crystals are of few mm in size. XRD patterns of the samples reveal their crystalline nature. The FTIR spectrum shows the presence of water molecules and carboxylic acid. ICPAES measures the quantity of dopant in the pure crystal. The hardness measurement shows the variation of hardness values with load and dopant's concentration.
