Cordierite Refractory Brick Description
Cordierite Refractory Brick is a type of refractory material made primarily from cordierite, a magnesium aluminum silicate mineral known for its low thermal expansion, high thermal shock resistance, and good insulating properties. These bricks are specifically designed for applications where high resistance to thermal cycling (rapid heating and cooling) is required.

FAQs
Q1: What is Cordierite Refractory Brick?
Cordierite Refractory Brick is a type of ceramic brick made from cordierite, a mineral with excellent thermal shock resistance and low thermal expansion. It is commonly used in high-temperature applications, such as kilns, furnaces, and ovens, where consistent temperature resistance is required.
Q2: What are the temperature limits for Cordierite Refractory Brick?
Cordierite Refractory Bricks typically withstand temperatures up to 1,250°C (2,282°F). However, their performance may vary depending on the specific formulation and manufacturing process.
Q3: How does Cordierite Refractory Brick compare to other refractory materials?
Compared to other refractory materials like alumina or silicon carbide, cordierite bricks offer superior thermal shock resistance and lower thermal expansion. However, they may not be suitable for extremely high-temperature applications where materials like alumina or mullite would perform better.
