X-ray diffraction technique (XRD)

 

X-ray diffraction analysis (XRD) is an analytical technique to investigate qualitatively and semiquantitatively

the constituent compounds in a substance. It helps to understand and utilize the
fundamental relationship between structure and properties of materials. It can also provide
information which is either impractical or impossible to be obtained by many conventional
analytical techniques used in many industries.
X-ray diffraction (XRD) is used to identify minerals and materials by their atomic structure. A
wide variety of materials from pharmaceuticals to metallic powders can be analyzed and
identified by X-ray diffraction because crystallinity is the only prerequisite for analysis.
