Frequently Asked Questions (FAQ)

What are the primary materials used for ceramic honeycomb?

Ceramic honeycomb is primarily manufactured using Cordierite, Dense Cordierite, Cordierite-Mullite, Mullite, and Corundum-Mullite, each suited for varying temperature and industrial requirements.

What is the maximum operating temperature ceramic honeycomb can withstand?

Depending on the material composition, maximum working temperatures range from below 1300℃ (Cordierite) up to 1500℃ (Corundum-Mullite).

Can ceramic honeycomb sizes and cell densities be customized?

Yes, products can be customized according to your specific dimensional requirements, hole density (cpsi), wall thickness, and actual operating conditions.

Why is a low thermal expansion coefficient important for ceramic honeycomb?

A low thermal expansion coefficient ensures exceptional thermal shock resistance, preventing structural cracking or failure during rapid heating and cooling cycles.

What hole densities (cpsi) are typically available?

Standard cell configurations range from large open channels of approximately 0.7 cpsi (5×5 holes) up to dense structures of 100 cpsi (59×59 holes) or more.
