Ceramic heating element Ceramic heating element is a device that converts electrical energy into thermal energy. Its principle is based on the interaction of thermal effect and electrical effect.
First of all, the ceramic heating element is composed of ceramic material and resistance wire. When current passes through the resistance wire, the resistance wire generates heat, which is based on the principle of electrical effect. Heat is transferred into the ceramic material, causing it to heat up, based on the principle of thermal effect.
Secondly, ceramic materials have high resistivity and low thermal conductivity, which allows the heat generated by the resistance wire to be concentrated in the ceramic material without being lost to the surrounding environment. At the same time, the high temperature stability and chemical stability of ceramic materials also enable ceramic heating elements to have a longer service life.
