[Pronunciation: ceramic coil /sɪˈramɪk/kɔɪl/]
A ceramic coil can refer to any type of coil that uses a ceramic plate or mold in it’s design. Some ceramic coils simply have a ceramic rod with the coil wound around it, using the porous ceramic as a wick, others use the ceramic as a heating element by embedding resistance wire inside the ceramic itself, like in ceramic wafer atomizers.
The most common type of ceramic coil is the type that consists of a micro porous ceramic glass molded around the resistance wire. In these devices, the ceramic is mostly intended to act as a wick. Some still have an outer wrapping of cotton or other wicking material, but this is generally only there to serve as a seal and not used for wicking.
