High temperature resistance and high strength Refractory Cordierite sagger box
1. Description
Cordierite is a magnesium alumina silicate with chemical formula Mg2Al4Si5O18. It is normally used for applications that required high temperatures and are subject to thermal shock or require low thermal expansion materials, such as kiln furniture.
2. Key Properties
The main properties of Porous Cordierite are that it comprises magnesium aluminium silicate, has porous material structure , has a low mechanical strength, exhibits an increased resistance to thermal shock and has a low linear expansion.The key applications of Porous Cordierite are kiln furniture, pillars, saggers, kiln construction, element feed throughs and terminals, high voltage at high temperature electrical terminals, industrial fuse bodies, burner nozzles and expansion bars for thermostats.They are also able to manufacture a range of components to customer specification in various other technical ceramics such as alumina, zirconia, silicon carbide, steatite, boron nitride, cordierite, silicon nitride and Macor.
