Crystal Structure Analysis

AI Overview

X-ray Diffraction (XRD) is a non-destructive analytical technique used to identify crystalline phases, determine structural properties (crystallite size, strain, texture), and analyze amorphous materials. It is widely applied in materials science, pharmaceuticals, geology, and nanotechnology to analyze powders, thin films, and bulk materials. 

Key applications of XRD include:

• Phase Identification: Identifying crystalline phases and compound structures, including distinguishing polymorphs in pharmaceuticals.
• Quantitative Analysis: Determining the relative amounts of different phases in a mixture, often used in mineralogical studies and metallurgy.
• Crystal Structure & Lattice Parameters: Determining unit cell dimensions, lattice symmetry, and atomic positions.
• Microstructural Characterization: Estimating crystallite size (often at the nanoscale), lattice strain, and microstrain from peak broadening.
• Thin Film Analysis: Characterizing epitaxial growth, orientation, thickness, and roughness of thin films deposited on substrates.
• Residual Stress Measurement: Measuring internal stresses in materials generated by welding or mechanical treatment.
• Environmental & Geological Studies: Identifying clay minerals, analyzing soil composition, and identifying contaminants.
