Porous Cordierite Honeycomb Monolith

 

Ceramic honeycomb used for RTO application

Cordierite is a magnesium alumina silicate material, which has very low linear expansion, low coefficient of thermal expansion and excellent resistance to thermal shock. Cordierite also offers an excellent range of mechanical strength, porosity criteria, and excels in cost-effective extruded and dry-pressed forms.

Cordierite Honeycomb Monoliths are divided into two types: porous type and compact type.
