An analysis method used to determine the composition of a solid crystalline material. When an x-ray beam is transmitted through or reflected from a crystalline material, it is diffracted at varying angles due to the spacing of the atoms in the crystal. The pattern of the diffracted beam is analyzed and used to determine the atomic structure in the material. Samples may be in the form of a single crystal or crushed powder. The primary XRD reference collection is produced by JCPDS (Joint Committe on Powder Diffraction Standards) in conjunction with the International Centre for Diffraction Data (ICDD).

Description

An analysis method used to determine the composition of a solid crystalline material and to identify its crystalline structure. When an x-ray beam is transmitted through or reflected from a crystalline material, it is diffracted at varying angles due to the spacing of the atoms in the crystal. The pattern of the diffracted beam is analyzed and used to determine the atomic structure in the material. Samples may be in the form of a single crystal or crushed powder. The primary XRD reference collection is produced by JCPDS (Joint Committe on Powder Diffraction Standards) in conjunction with the International Centre for Diffraction Data (ICDD).
