Cordierite Ceramics

Cordierite ceramic is a magnesium aluminum silicate material that has been widely used in applications where thermal shock resistance is important. Cordierite ceramic is also useful because it has a low thermal expansion and good electrical insulation compared to other ceramic materials.

Can you provide samples for me to test? How much does it cost?

We strive to provide ceramic samples that closely meet your requirements to the best of our abilities.
The samples are completely free, but you need to pay the freight.
For samples with unique shapes that require custom molds, we are open to discussing the mold cost in order to accommodate your specific needs.

We don’t know which material of ceramic we need, what should we do?

No worries! Please provide us with more details about your requirements, such as the intended use, desired properties, and any specific characteristics you're looking for.

With these information, our team can guide you in selecting the most suitable ceramic material for your needs.

We are concerned about the quality of the product we ordered.

We understand your worries and we maintain stringent quality control standards as following:

Test Standard Testing Dimension Pass Rate Standard Range
Appearance Inspection Quantity and Severity of Defects ≥ 97.3% Determined by AQL standard
Dimensional Inspection Size Accuracy and Consistency ≥ 98.1% Determined by ISO 9001 standard
Density Testing Material Density ≥ 97% Determined by ASTM C20 standard
Hardness Testing Surface Hardness ≥ 98.2% Determined by ISO 6508 standard
