Ceramics & Glass Testing & Analysis

Ceramics & Glass Testing & Analysis

Ceramics and glass can perform extremely well, but small defects can determine when they fail. Pores, unwanted phases, surface damage, or cracks caused by thermal stress can significantly reduce the strength and reliability of brittle materials.MatX Lab analyses ceramics and glass to confirm composition and phase, measure properties such as density, porosity, strength, and hardness, and investigate the reasons behind cracking or failure. Our testing looks at the material structure, chemistry, and defects that influence the performance and durability of brittle materials.

What We Analyze in Ceramics & Glass

MatX Lab analyzes phase, density, and mechanical behavior. We validate that the material is the intended phase and composition, measure the porosity and strength that govern reliability, and find the flaws behind brittle failure. The same methods that qualify a batch also define a fracture.

• Phase and crystal structure.
• Composition, purity, and trace contaminants.
• Density, porosity, and water absorption.
• Flexural strength, hardness, and fracture toughness.
• Thermal expansion and thermal-shock behavior.
• Internal defects and fracture origins.

How We Test Ceramics & Glass

Ceramic work usually combines structural and mechanical methods with defect inspection, and we scope the combination your question needs. The methods below are the ones we reach for most, and each links to its own page.

Structural Characterization:

Identifies phase and crystal structure by X-ray diffraction. It confirms the ceramic is the intended phase and detects unwanted or secondary phases that change properties.

Imaging & Microscopy:

Examines grain structure, porosity, second phases, and fracture surfaces. Fractography reads the origin of a break, which in a brittle material is usually a specific flaw.

Mechanical Testing:

Measures flexural strength, hardness, and fracture toughness. These properties confirm whether a ceramic or glass meets its mechanical specification and how tolerant it is of flaws.

Elemental Analysis:

Examines purity, composition, and traces of contaminants that could affect performance. Accurate verification is crucial since even slight compositional changes might affect sintering behavior, strength, and electrical characteristics.

Thermal Analysis:

Evaluates the characteristics that underlie dimensional stability, thermal-shock resistance, and thermal expansion, transitions, and stability throughout temperature.

3D Characterization:

Maps internal porosity, cracks, and inclusions by X-ray CT without breaking the part, useful when the defect is buried.

Failure Analysis:

Determines whether a ceramic or glass failed by an internal flaw, a surface defect, thermal shock, or overload, combining fractography and microstructure to a root-cause conclusion.

Industries That Rely on Ceramics & Glass Testing

Ceramics and glass testing spans sectors that depend on hard, high-temperature, or electrically functional materials, where a single flaw can end a part's life.

Standards & Test Methods

Ceramics and glass testing follows the methods defined by your requirements and specifications. Where a recognized standard applies, we use that method and reference it in the report. The testing approach is documented clearly so the results can be traced back to the required method.
