Mullite ceramics are high temperature ceramic material with good mechanical strength, and excellent thermal shock properties due to its relatively low thermal expansion coefficient. Mullite ceramic is a good lower cost alternative to dense alumina. Typical applications include, but are not limited to, thermocouple applications, furnace muffle tubes, kiln rollers, sight tubes, rods and kiln furniture.
