Powder X-Ray Diffractometer which is commonly known as PXRD was recently installed in the Postgraduate Institute of Science, University of Peradeniya. This instrument is a high end instrument with latest development in PXRD instrumentation. X-ray diffraction is a process in which X-rays fall on a crystalline material are reflected by the atoms, which are arranged in ordered arrays, if certain geometrical conditions are met. Since, the resulting X-ray diffraction pattern is a characteristic feature of the material, this technique is used as a high precession material identification method. The Bruker D8 Advanced Eco Powder X-ray Diffraction system can be used for nearly all X-ray diffraction applications, such as qualitative and quantitative phase analysis, stress and texture measurements, particle size analysis, GIXRD and structure determination
