What is a ceramic heater?

Scientific principles of ceramic heaters. Ceramic heaters are electric heaters that use positive temperature coefficient (PTC) ceramic heating elements to generate heat through the resistance heating principle. Ceramic materials have sufficient electrical resistance and thermal conductivity to generate and conduct heat when electrical current flows through them. They offer high strength and durability. Therefore, they perform very well when used as heating elements.

The heating element of a ceramic heater is made of pure ceramic material, but most are composite materials encapsulated by metal and ceramic materials. The ceramic material in the latter acts as an insulator but at the same time conducts heat to the surrounding environment, minimizing the heat and energy losses associated with uninsulated resistance wires.

Ceramic heaters are used in a wide range of industries such as drying, boiling, shaping and melting products. Ceramic heaters are widely used for space heating, providing a fast, safe and clean heat source.
