EDXRD

EDXRD stands for Energy Dispersive X-ray Diffraction. It is a technique used to study the crystallographic structure of materials. Unlike traditional angle dispersive X-ray diffraction (ADXRD) which measures the diffraction angle at a fixed X-ray wavelength, EDXRD utilizes a broad spectrum of X-ray energies at a fixed diffraction angle. As X-rays of different energies interact with the crystal lattice, they are diffracted according to Bragg's law, but with energy as the varying parameter rather than angle. The diffracted X-rays are detected, and their energies are analyzed. Peaks in the resulting energy spectrum correspond to specific crystallographic planes within the material, with the energy of the peak being inversely proportional to the d-spacing of the planes. This allows for the determination of lattice parameters and phase identification. EDXRD is particularly useful for in-situ studies, such as under high pressure or high temperature, as the experimental setup is simplified and often requires less space compared to ADXRD. It can also be advantageous for analyzing complex samples or when studying materials with rapid structural changes.
