Home > What We Do > XRD Testing 


Our skilled analytical team at IMR Metallurgical Services, centrally located in Louisville, KY, offers XRD analysis on a variety of inorganic compounds, including oxides, nitrides and carbides.  With our new Rigaku Miniflex 600 XRD analyzer, we can offer identification of crystalline phases, percent crystallinity and crystalline size.  

This analytical technique has many applications, including:

  • Identification of Unknown Powders
  • Analysis of Corrosion Products
  • Phase Identification
  • Compound Morphology
  • Crystal Structure
  • Reverse Engineering
  • Competitive Analysis
  • Material Confirmation 
  • Differentiation of Compounds with the Same Elements (eg: Fe2O3 vs. Fe3O4)

We also can provide XRD analysis of hydroxyapatite (HA) to include specification ISO 13779.  We offer Ca:P ratio, percent crystallinity, foreign phases analysis and more.  Contact Andy Waldron below for a quote or more information on hydroxyapatite testing services including XRD analysis, chemical composition or additional services.

How does XRD work?

A focused X-Ray beam is shot at the sample at a specific angle of incidence.  The X-Rays deflect or "diffract" in various ways depending on the crystal structure (inter-atomic distances) of the sample.

The locations (angles) and intensities of the diffracted X-Rays are measured.  Every compound has a unique diffraction pattern.

In order to identify a substance, the diffraction pattern of the sample is compared to a library database of known patterns.

Peak shapes and intensities give information about percent crystallinity and crystalline size.  Our analytical team then provides you with a clear, concise report, outlining the properties of your material in easy to understand language.
