GROWTH AND STUDIES OF PURE AND AMMONIUM OXALATE MONOHYDRATE DOPED POTASSIUM DIHYDROGEN PHOSPHATE SINGLE CRYSTALS

Abstract

Optically good quality single crystals of pure and ammonium oxalate monohydrate doped Potassium dihydrogen phosphate (KDP) were grown from aqueous solution employing slow evaporation technique. The crystallinity and cell parameters of the grown pure and ammonium oxalate monohydrate doped KDP crystals were studied by powder X-ray diffraction analysis. The mechanical strength of the grown crystals was analyzed by Vickers microhardness test. The functional groups present in the grown crystals were identified by Fourier transform infrared studies. The various investigations indicate changes in structural, mechanical and spectroscopic properties of the KDP crystal due to the incorporation of ammonium oxalate monohydrate into the KDP crystal lattice.
