Description of Mullite Ceramic Heater Plate
Mullite Ceramic Heater Plate is a type of heating element that is made from mullite (3Al2O3·2SiO2), a silicate mineral of aluminum and silicon. Mullite ceramics are known for their excellent thermal properties, including high temperature resistance, thermal shock resistance, and good mechanical strength, making them an ideal material for use in heater plates and other high-temperature applications.
