Heat resist element refractory plate porous ceramic cordierite honeycomb
Cordierite ceramic
Cordierite ceramic is one of the most popular ceramics for its properties of excellent thermal stability, high refractoriness, good chemical durability, low dielectric constant, and low thermal expansion.
Infrared Honeycomb Ceramic Plate, mainly for gas-fired infrared burners. Such a ceramic plate by honeycomb ceramic plate surface to improve the simple planar corrugated staggered three-dimensional, increasing the specific surface area and combustion area, which play a regenerative combustion role to achieve more complete combustion flame seedlings to reach the infrared burner heating effect, in order to achieve low power consumption and high environmental requirements.
