"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.

Kyocera will be happy to help you select the appropriate material for your needs.

Silicon nitride heater


Kyocera's silicon nitride (SN) heater has been developed and mass-produced as a glow plug for cold-start assistance of diesel engines with excellent durability at high temperatures. In addition to glow plugs, Kyocera has been providing SN heaters to residential and industrial markets as well, such as igniters for residential gas furnace and heaters for die-bonding machines.

    Ecology / Energy Gas appliances

    Gas appliances

    SN heaters are used as the igniter in all gas appliances, including residential gas furnaces, gas boiler, etc. Kyocera's SN heater achieves quick and stable ignition because of its rapid heating performance, and high reliability contributes to long life and savings on maintenance for end-users. Also, the SN heater offers noise less ignition in contrast to a spark plug.

  • Mobility

    Mobility Glow plug

    Glow plug

    Glow plugs are used for cold-start assistance for diesel engines. They contribute to exhaust gas purification at the engine starting phase due to the fast heating speed of Kyocera's SN heater and high reliability in harsh environments.
