# XRD analysis & X-Ray Diffraction testing laboratory

## What is X-ray Diffraction (XRD)?

X-ray diffraction (XRD) is an analytical technique used to study the different phases of matter and crystalline materials.

XRD thus makes it possible to identify the crystalline compound(s) present in a material, as well as their crystallographic forms.

Our experts can assess your requirements and recommend the most suitable analytical approach for phase identification, crystallographic characterization, contamination investigation, or quality control purposes.

**👉 Contact our team at [contact@filab.fr ](mailto:contact@filab.fr) ****or fill out the form on the right to discuss about it.**

### XRD analysis using the Rietveld method...

As for quantitative analysis by refinement using the Rietveld method or by specific calibration, this allows the determination of the concentrations of these compounds in both trace and major amounts.

Thus, the applications of this technique are numerous, particularly in the fields of metallurgy, ceramics, pharmaceuticals, and device meds.

### Complementarity and coupling with other technical means

XRD analysis becomes more effective when combined with other methods available at the FILAB laboratory. This multi-technique approach enhances our understanding of materials and facilitates comprehensive characterization.

- Combining XRD and [SEM/EDS](https://filab.fr/en/our-technical-resources/laboratory-analysis-sem-scanning-electron-microscopy/sem-particulates-analysis.md) allows us to link crystal structure and morphology.
  Coupling with [DSC](https://filab.fr/en/our-technical-resources/laboratory-analysis-dsc-calorimetric.md) or [TGA](https://filab.fr/en/our-technical-resources/tga-tga-ftir-and-tga-ms-analysis-at-filab-laboratory.md) provides information on thermal transitions, stability, and phase transformations.
- Furthermore, spectroscopic techniques such as [FTIR](https://filab.fr/en/our-technical-resources/laboratory-analysis-ftir-spectroscopy.md) complement the interpretation by providing data on chemical composition and molecular state.

### The role of an XRD testing laboratory

An **XRD testing laboratory** is a specialized facility equipped with advanced X-ray diffractometers, trained personnel, and data analysis tools. These labs offer a wide range of services, from powder **X-ray diffraction (PXRD)** to in situ high-temperature measurements, and even small-angle**X-ray scattering (SAXS)** for nanoscale analysis.

Here’s what makes a professional lab indispensable:

**Accurate sample preparation**: proper grinding, mounting, and orientation

**Data interpretation expertise**: ability to use software for Rietveld refinement, phase quantification, and crystallographic indexing

**Customized reports**: clear, detailed documentation tailored to client needs

**State-of-the-art instruments**: with high-resolution detectors and goniometers

**Fast turnaround times**: crucial for production workflows or time-sensitive projects

Whether you’re outsourcing to a contract lab or working with an in-house facility, choosing a reputable **XRD testing provider** ensures reliability and regulatory compliance.

## Information obtained through XRD analysis

XRD analysis is used to identify and quantify the phases present in powders, alloys, ceramics, catalysts, pigments, partially crystallized glasses, or pharmaceuticals. It provides**precise structural data**:

  nature of crystalline phases, degree of crystallinity, sizes and shapes of crystallites, lattice parameters, relative phase distribution, detection of minor or spurious phases, highlighting structural transitions.
By combining diffractograms with reference databases, the FILAB laboratory can confirm the **conformity** of a batch of material, highlight **polymorphism**, or identify the origin of **degradation.**

For **metallic materials**, XRD also makes it possible to assess residual austenite, the presence of carbides, or the state of internal stress.

### Materials analyzed using XRD at the FILAB laboratory

**X-ray diffraction is a method of physicochemical analysis.** This analysis is exclusively for crystalline materials, such as minerals, metals, ceramics, and composites. It is generally not applicable to liquids.

Furthermore, X-ray diffractometry allows for the differentiation of products with the same basic chemical composition but different crystallization patterns, particularly in materials such as silica, steel, and alloys.

### XRD analysis on powder for the pharmaceutical industry

In the pharmaceutical sector, powder X-ray diffractometer allows us to:

- determine the crystalline structure of drugs
- identify the individual components of complex drugs
- verify the purity and quality of raw materials

### XRD analysis of metals

X-ray diffractometry on minerals and natural solids allows us to:

- determine the crystalline structure of metals
- determine residual stresses in welds, coatings, and forgings, in order to prevent premature failures

### XRD analysis of minerals and natural solids

X-ray diffractometry on minerals and natural solids allows us to:

- identify and characterize mineralogical phases
- determine the mineralogical composition, crystalline structure, and physical properties
- understand the origin, evolution, and environmental impact of a material

## FAQ

 What is XRD analysis used for?
XRD (X-ray Diffraction) analysis is used to identify and characterize the crystalline structure of materials. It helps determine phase composition, crystallinity, crystal size, lattice parameters, and can detect structural defects. Industries like pharmaceuticals, metallurgy, geology, and construction frequently use XRD testing to ensure product quality and material performance.

 Can you analyze both powders and solid samples?
Yes. Our XRD testing laboratory is equipped to analyze powders, bulk solids, coatings, thin films, and even small devices. If you're unsure how to prepare your sample, our team will guide you through the process.

 Is XRD analysis destructive?
No, XRD is a non-destructive technique, meaning your sample remains intact during and after the test. This makes it ideal for valuable prototypes, heritage objects, or forensic materials.

 Do you provide interpretation and consulting?
Absolutely. At Filab, we don't just send raw data—we offer complete analytical reports including interpretations, comparisons with standards, and tailored recommendations based on your application or industry.

 Can XRD be used to determine crystal size?
Yes. Using line broadening and peak analysis, XRD can estimate average crystallite size in nanomaterials or fine powders. This is particularly useful in the development of catalysts, pigments, and nano-engineered materials.

 How do I submit a sample for XRD testing?
You can contact us via our website or email to request a quote. We’ll then guide you through packaging and shipping instructions. Local clients may also drop off samples directly at our lab.

 What is the difference between XRD and XRF?
XRD (X-ray Diffraction) identifies crystal structure and phases, while XRF (X-ray Fluorescence) provides elemental composition. These techniques are complementary, and Filab can offer both if needed for comprehensive material characterization.

 What types of samples can be analyzed by XRD?
XRD can analyze powders, bulk solids, thin films and single crystals. FILAB routinely examines pharmaceutical powders, metallic components, minerals and ceramic materials.

 How does XRD detect residual stress in metals?
Residual stress causes slight shifts in diffraction peak positions. By measuring these shifts, XRD calculates stress values non-destructively, which is essential for aerospace and automotive components.

 What is the Rietveld method in XRD analysis?
The Rietveld method is a computational approach that refines a theoretical diffraction pattern to match experimental data. It provides quantitative phase analysis, crystallite size and lattice parameter determination.
