Mullite is a high temperature ceramic material with good mechanical strength and excellent thermal shock properties due to its relatively low thermal expansion coefficient. Mullite 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.
