Characterization of ceramics according to ISO 13925-2 by XRD
As an industrialist you would like to carry out a ceramic characterization according to ISO 13925-2
Expertise at the service of the reliability of your ceramic components
Technical ceramics are widely used in industry for their high mechanical, thermal, and chemical properties. Their performance depends directly on their mineralogical composition and the crystalline phases present in the material.
ISO 13925-2 describes a method for identifying and characterizing the crystalline phases of ceramic materials by X-ray diffraction (XRD).
At the Filab laboratory, our teams support manufacturers in the identification and characterization of ceramics, ensuring the reliability of their processes and applications.
Our ceramic analysis services by XRD according to ISO 13925-2
The crystalline composition of a ceramic directly influences its performance. X-ray diffraction (XRD) analysis according to ISO 13925-2 allows us to:
- identify the crystalline phases present in the material
- verify the mineralogical composition of a ceramic
- compare several materials or suppliers
- validate a manufacturing or sintering process
- detect the presence of undesirable phases
Characterization of ceramics by XRD according to ISO 13925-2: an expertise of the FILAB laboratory
Why choose FILAB for ceramic characterization by XRD according to ISO 13925-2?
X-ray diffraction (XRD) allows for the analysis of the crystalline structure of materials.
When an X-ray beam interacts with a crystalline material, it generates a characteristic diffraction pattern. This signal acts as a true mineralogical fingerprint, allowing for the identification of the phases present.
This technique is particularly well-suited to the study of ceramics containing, for example:
- alumina
- zirconia
- mullite
- quartz
- carbides or nitrides
The analysis can also be used to estimate the relative proportions of the different phases present in the material.
Why perform ceramic characterization by XRD according to ISO 13925-2?
- Verification of the composition of a production batch
- Conformity of a material to specifications
- Comparison of ceramic formulations
- Optimization of sintering parameters
- Identification of a phase transformation
- Understanding the origin of material degradation

Which industrial sectors use ceramics?
What is ceramic characterization and analysis ?
Ceramic characterization involves assessing the material's identity: its chemical composition, crystal structure, microstructure (grain size, porosity), as well as its physical and mechanical properties.
This material analysis also covers thermal properties, such as heat resistance and dimensional stability at high temperatures. This is a crucial step in understanding the material's behavior and optimizing its in-service performance.
For example, characterizing a technical ceramic helps ensure it meets specific application requirements (thermal resistance, chemical inertness, mechanical hardness, etc.) or identify the root causes of potential failures.
Our FAQ
Unlike routine analysis, ISO 13925-2 specifies strict procedures for the quantitative analysis of phases. It imposes criteria on sample preparation (particle size, flatness), instrument settings, and calculation methods (often using Rietveld refinement). This ensures traceability and precision, which are essential for critical sectors.
This method is applicable to a wide range of technical ceramics, including:
- Oxides: Alumina ($Al₂O₃), Zirconia ($ZrO₂), Titanium ($TiO₂).
- Non-oxides: Silicon carbides ($SiC), Silicon nitrides ($Si₃N₄).
- Complex ceramics: Ceramic matrix composites (CMCs) and bioceramics (Hydroxyapatite).
XRD is primarily dedicated to crystalline phases. However, according to ISO 13925-2, it is possible to estimate the glassy (amorphous) phase content by adding an internal standard (external or internal standard method), which allows you to quantify the non-crystalline fraction of your material.
Chemical analysis determines the elemental composition of a material (presence of aluminum, silicon, zirconium, etc.).
X-ray diffraction, on the other hand, identifies the crystalline structure and the mineral phases formed by these elements.
These two approaches are complementary for fully characterizing a ceramic material.
