XRD Crystallography Analyzer

Purpose

The XRD Crystallography Analyzer skill provides crystallographic characterization of nanomaterials through X-ray diffraction analysis, enabling phase identification, crystallite size determination, and structural refinement.

Capabilities

Phase identification and Rietveld refinement
Crystallite size (Scherrer equation)
Lattice parameter calculation
Preferred orientation analysis
In-situ XRD capabilities
PDF (Pair Distribution Function) analysis

Usage Guidelines

XRD Analysis

Phase Identification
- Match peaks to database entries
- Identify multiple phases
- Assess phase purity
Crystallite Size
- Apply Scherrer equation: D = Kl/(B cos theta)
- Account for instrumental broadening
- Use Williamson-Hall for strain
Structural Refinement
- Perform Rietveld refinement
- Extract lattice parameters
- Quantify phase fractions

Process Integration

Multi-Modal Nanomaterial Characterization Pipeline
Structure-Property Correlation Analysis
Nanoparticle Synthesis Protocol Development
