Material Details
Cordierite ceramic is a magnesium aluminum silicate material that has been widely used in applications where thermal shock resistance is important. Cordierite ceramic is also useful because it has a low thermal expansion and good electrical insulation compared to other ceramic materials. It can be formed into a variety of complex geometries by employing several types of manufacturing process such as axial pressing, isotactic pressing, injection molding and extrusion.
