Dyfrakcja promieniowania rentgenowskiego - metoda proszkowa - użyteczna technika badania związków chemicznych

Various techniques are available for the investigation of the solid state. Among them X-ray powder diffraction (XRPD) is a very powerful and widely analytical tool to study powder properties. We can obtain many informations from XRPD: * from peak positions - holoedry, unit cell size /lattice constants/, * from peak intensities - unit cell contents /atom positions, etc./, * from peak shapes - crystallite size, nonuniform strain, extended defects, so there are many applications of XRPD: * quantitative phase termination qualitative phase identification * amorphous/crystalline characterization - polymorph discrimination * phase transformation study * impurity analysis Nowadays, XRPD plays an important role in analysis many materials such as pharmaceuticals, ceratnics, minerals, metals, alloys, inorganic and organic chemicals, corrosion products and microelectronic materials.
