Electrical Resistivity of Ceramic Materials
Ceramics typically exhibit high electrical resistivity compared to metals and conductive materials. This high resistivity is due to the nature of the crystal structure and the insulating properties of ceramics.
The following table provides a comprehensive list of electrical resistivity values for common ceramics at standard room temperature (approximately 20°C or 68°F) and 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
