Growth of calcium hydrogen phosphate dihydrate ( chpd ) crystal and characterization studied by spectral method

Calcium hydrogen phosphate dihydrate [CaHPO 4 .2H O] a dissolved mineral in urine. It causes stones in renal or bladder in living organisms. Calcium hydrogen phosphate dihydrate has been crystallized in silica gel by single diffusion technique. The crystals had rregular shape like square. XRD results confirmed that the product of CHPD with dentical crystal structures. Thermal and spectral properties are analyzed using Fourier ransform infrared spectroscopy (FTIR) powder X-ray diffraction ( XRD ), scanning electron microscopy (SEM ) with Energy dispersive spectrum (EDS ). Above studies and results are discussed. 2
