Description

Cordierite CAS NO 1302-88-1 is a magnesium aluminosilicate mineral valued for its exceptional thermal stability and low coefficient of thermal expansion. This makes it a critical material for applications requiring resistance to thermal shock and high temperatures. It is primarily utilized in the manufacturing of advanced ceramics, catalytic substrates, and high-performance refractory components.

Application

• Manufacturing of catalytic converters and diesel particulate filters for automotive exhaust systems.
• Production of high-temperature kiln furniture (saggers, setters) and refractory linings.
• Key raw material in advanced technical ceramics for electronics and thermal management.
• Essential component in honeycomb ceramic substrates used in chemical processing and filtration.
• Used in the synthesis of porous ceramics for membrane and insulation applications.
• Base material for infrared-transmitting radomes and windows.

Quality Control

Our Cordierite is produced and tested under a rigorous quality management system to ensure batch-to-batch consistency and performance. Key parameters such as phase purity, chemical composition, and particle size distribution are strictly controlled. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from incompatible materials such as strong acids or fluorides. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent moisture absorption.
