Cordierite ceramics are primarily used in industrial applications including ceramic kiln shed plates, saggars, electronic packaging materials, catalyst carriers, foam ceramics, bioceramics, and high-temperature thermal radiation materials. With limited natural reserves and low-grade availability, most cordierite materials are artificially synthesized.
This material offers exceptional properties including low thermal expansion coefficient, high compressive strength, and excellent fire resistance, making it ideal for refractory industry applications. Its thermal shock resistance makes it particularly valuable for high-temperature environments.
