Ceramics and refractories elastic moduli characterization
The brittleness of ceramic materials and the presence of aggregates are not obstacles for the elastic modulus measurement by Sonelastic® Systems. It does not apply static loads to perform the characterization of the elastic moduli, only small amplitude impulse excitation and vibration.

Sonelastic® relies on the Impulse Excitation Technique for accurate and non-destructive characterization of elastic moduli (E, G and Poisson ratio) and damping of materials in accordance with the ASTM E1876, C1259 and C1548 standards. The characterization of both damping and elastic moduli reveals information about the presence and evolution of cracks, micro-cracks and defects in the material, as well as phase transformations.

Applications
Sonelastic® Systems have a wide range of applications for ceramic and refractory materials:
- Design and monitoring of firing cycle.
- Quality control of post-firing.
- Detection of cracks, micro-cracks and delamination.
- Study of oxidation, corrosion and cooking process.
- Thermal shock damage assessment.
- Finite element modeling refinement.
Sonelastic® Systems are suitable for testing:
- - Technical ceramics.
- - Electronic ceramics.
- - Traditional ceramics (roof tiles, bricks and white wares).
- - Pre-shaped refractories:
- High alumina (electrofused alumina and tabular).
- Alumina (alumina-chromium, alumina-carbon, alumina-spinel, etc.).
- Antacids and Insulators.
- Magnesians (magnesia-carbon, magnesia-chrome and magnesia-spinel).
- Mullite and mullite-zirconia.
- Chemically bound.
- Silico-aluminous.
- - Refractory castables:
- Dry / wet mortars.
- Self-flow / vibrated.
- Zero / low cement.
- Grip ceramic / phosphate.
- Projection / punch / projection.
- Insulators.
Resistance to thermal shock damage is an important feature of refractories because since it determines their performance and lifetime in various applications. The use of more sensitive and non-destructive techniques for the evaluation of damage is highly desirable to facilitate the development and quality control of these materials. It also helps understanding the microstructural changes that occur in the damaged material.
