Ceramics as Electrical Conductors

Ceramics are usually thought of as electrical insulators and indeed a great many of them are. Since the first uses of electricity it has been necessary to have good electrical insulators to isolate current-carrying 

The distinction between materials as electrical conductors and materials as insulators was made in the eighteenth century. Although historically the insulating properties of ceramics have often been one of their most 

In 1881 Godaiming became the first town in the world to have a public electricity supply. 

The conduction mechanisms in ceramics can be quite complex and may involve the movement of electrons. 

In comparing values of o and p it is useful to remember the simple relationship between them
