Powder X-ray diffractometry

Powder diffractometer is used to analyze inorganic materials. X-ray diffraction analysis (XRD) is used to identify crystalline compounds. All crystalline compounds, such as minerals, have unique crystallographic structures and XRD can be used to identify these compounds comparing their diffraction data against a database of known minerals and compounds. XRD is used to identify minerals, rocks, gemstones, corrosion products of metals, old conservation materials (e.g. fillers and colourants) such to mention of few.
