Mullite Ceramic

Ceramic Resistor Cores

Du-Co Ceramics manufactures mullite ceramic components for demanding high-temperature applications requiring excellent thermal shock resistance and dependable mechanical strength. Mullite is an alumina-silica ceramic material that offers a unique combination of low thermal expansion, good strength, and cost-effective performance, making it an excellent alternative to dense alumina in many industrial applications. Mullite ceramics are commonly used in furnaces, kilns, thermocouples, and other applications exposed to repeated heating and cooling cycles.
