- Commodity name: cordierite
Introduction:
Cordierite is a high-performance glass-ceramic characterized by low thermal expansion, excellent high-temperature resistance, and superior thermal shock resistance. It also exhibits high infrared transmittance and excellent dimensional stability, making it well suited for harsh high-temperature service conditions.

Applications:
· Optical equipment thermal isolation base, mirror tube support, and optical path fixation components
· High-temperature laser equipment heat-sink base and heating chamber substrate
· Precision mounting fixture for semiconductor equipment
· Infrared light source heat‑shielding bracket, optical instrument heat‑shielding frame
· Lightweight, high-temperature-resistant structural components for aerospace optoelectronic equipment
