Top best answers to the question «Can ceramic conduct electricity»
Most ceramics resist the flow of electric current, and for this reason ceramic materials such as porcelain have traditionally been made into electric insulators. Some ceramics, however, are excellent conductors of electricity… In ceramics the ionic bonds holding the atoms together do not allow for free electrons.

Electric conductivity in ceramics, as in most materials, is of two types: electronic and ionic. Electronic conduction is the passage of free electrons through a material. In ceramics the ionic bonds holding the atoms together do not allow for free electrons.
Steel ball bearings can conduct electricity whereas full ceramic bearings, hybrid ceramic bearings and plastic bearings are non-conductive. In a steel bearing, current passes from inner ring to outer ring via the balls. This often occurs in electric motors and generators and applications where there is a build-up of static electricity.
Ceramics resist moisture, do not conduct electricity, and can withstand temperatures higher than molten metals. Propose some uses of ceramics.
A team of engineers from the famed Fraunhofer Institute has developed a super-efficient ceramic fuel cell that can be used in the home to generate both electricity and heat from natural gas.
Is ceramic a conductor or insulator of heat? As a general rule, substances which are good conductors of heat are also good conductors of electricity. Thus, all metals are conductors, whereas air, (pure) water, plastics, glasses, and ceramics are insulators.
Though Fine Ceramics (also known as "advanced ceramics") are generally insulating materials that block electricity, semiconductor ceramics can be created to conduct electricity depending on their temperature and the level of voltage applied.
It can conduct electricity due to the vast electron delocalization within the carbon layers (a phenomenon called aromaticity). These valence electrons are free to move, so are able to conduct electricity. Why is graphite a semiconductor?
