Ceramic and semiconductor

Molybdenum disilicide (MoSi2) an intermetallic compound, a silicide of molybdenum, is a refractory ceramic primarily used in heating elements. It has moderate density, melting point 2030 °C (3686 °F) and is electrically conductive. At high temperatures it forms a passivation layer of silicon dioxide, protecting it from further oxidation. The application area includes glass industry, ceramic sintering, heat treatment furnaces and semiconductor diffusion furnaces.

Silicon nitride. New generation hot surface igniter for gas furnace and diesel engine glow plug are made of silicon nitride material. Such heating element or glow plug reach a maximum temperature of 1400 °C and are quick to ignite gasoline or kerosene. The material is also used in diesel and spark ignited engines for other combustion components and wear parts.

PTC ceramic elements: PTC ceramic materials are named for their positive thermal coefficient of resistance (i.e., resistance increases upon heating). While most ceramics have a negative coefficient, these materials (often barium titanate and lead titanate composites) have a highly nonlinear thermal response, so that above a composition-dependent threshold temperature their resistance increases rapidly. This behavior causes the material to act as a self-regulating heater, since current passes when it is cool, and does not when it is hot.  Thin films of this material are used in heating garments,  in automotive rear-window defrost heaters, and honeycomb-shaped elements are used in more expensive hair dryers, space heaters and most modern pellet stoves. Such heating element can reach a temperature of 950-1000 °C and are praised for the speed of temperature and stability.

Quartz halogen infrared heaters are also used to provide radiant heating.
