Understanding the Working Principles of Ceramic Heating Elements
Ceramic heating elements operate on the principle of electric resistance heating. When an electric current passes through a ceramic material with high electrical resistance, it generates heat due to the material’s intrinsic resistive properties. This process, known as Joule Heating, allows for efficient thermal energy conversion.
Unlike metal heating elements, ceramic materials have superior thermal stability and low thermal expansion, which enables them to withstand high temperatures without deformation. The thermal output depends on the material’s resistance, the electrical load, and the current flowing through the element.
