Crystal Structure & Phase Composition Intelligence
X-ray Diffraction (XRD) Analysis
From Diffraction Patterns to Structural Control
When X-rays interact with a crystalline material, they scatter according to atomic spacing. The resulting diffraction pattern is a structural fingerprint that reveals:
Phase composition
Crystal structure and symmetry
Degree of crystallinity
Lattice parameters
Residual stress and strain
At G-Hexa, XRD is not merely pattern matching — it is crystallographic interpretation that connects atomic arrangement with mechanical performance, thermal stability, corrosion resistance, and functional reliability.
By correlating diffraction data with processing conditions, we bridge structure with manufacturing control.

Expert Sample Preparation Workflow
Accurate diffraction results require optimized sample preparation to ensure representative and reproducible data.
- Powder grinding for uniform particle size distribution
- Randomized sample mounting to minimize preferred orientation
- Thin film alignment and substrate correction
- Surface smoothing for bulk samples
- Calibration using standard reference materials
- Repeated scans for validation and noise reduction
Each measurement is optimized to preserve true vibrational signatures.
Challenges in XRD Analysis
Preferred orientation, overlapping peaks, low crystallinity, and fluorescence effects can complicate interpretation. Complex multiphase alloys may require advanced refinement methods.
Our expertise ensures:
Accurate separation of overlapping diffraction peaks
Reliable identification of minor phases
Correct amorphous content estimation
Robust Rietveld modeling for quantitative analysis
Diffraction patterns are interpreted structurally — not just visually.
