Cordierite 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.
Cordierite is extensively used in important industrial applications
such as micro electronics, refractory products, heat exchanger for
gas turbines, thermal shock-resistant table ware, catalyst
supports, and porous ceramics. Low-expansion cordierite is suitable
for being applied at high temperature circumstance where a good
thermal shock resistance is required.This unique property of
cordierite is caused by the negative lattice expansion in c-axis
direction,which provides excellent resistance to thermal shock as
well as low thermal conductivity.
