"Fast heating"

Kyocera's ceramic heater is widely used in industrial and automotive applications. Taking advantage of our unique ceramic lamination technology and more than 30 years of experience, Kyocera's heater can deliver robust quality with outstanding performance. The highly reliable ceramic heaters allow customers to minimize the size of the heater while maintaining maximum wattage to support a rapid heating rate. Kyocera works with each customer to provide open-source tools or customized designs to meet your unique performance needs.


Kyocera's ceramic heater has a structure in which a heating element is built into the base ceramic material and is integrated by simultaneous sintering. This structure can completely shut out the outside air, and by embedding multiple circuits, it can also be equipped with an output switching function and a temperature sensor function.

    Semiconductor Electrostatic chuck (ESC)

    Electrostatic chuck (ESC)

    Electrostatic chucks (ESCs) are used in semiconductor manufacturing equipment for adsorption/fixation of wafers/temperature control. Since extremely precise dimension/temperature control is required in the semiconductor manufacturing process, Kyocera's unique pattern simulation and trimming technology achieves minimal dimensional variations and in-plane temperature distribution, contributing to high-quality semiconductor manufacturing.

  • Ecology / Energy

    Ecology / Energy Shower toilet

    Shower toilet

    Alumina heater is used as a water heater for bidet toilets to warm the water before showering. Due to quick heating functionality, the preheating tank can be removed, contributing to space savings and power consumption reduction. In addition, the high watt density of the alumina heater also contributes to the miniaturization of the heater unit itself.

  • Mobility

    Mobility Gas sensor

    Gas sensor

    Some of gas sensors use a heater to activate the sensor function. For automotive applications, it is used in oxygen sensors in the exhaust system. Kyocera's heater has high durability and rapid heating performance, which contributes to sensor reliability and shorter start up time.
