Ceramic Volume Resistivity

This current must be measured under steady state conditions that is neither a charging current nor a space charge buildup.

Ceramic volume resistivity. They provide high wear heat and corrosion resistance as well as high tensile strength volume resistivity dielectric strength and modulus of elasticity. Resistivity is commonly represented by the greek letter ρ. Electrical resistivity also called specific electrical resistance or volume resistivity and its inverse electrical conductivity is a fundamental property of a material that quantifies how strongly it resists or conducts electric current a low resistivity indicates a material that readily allows electric current. Volume resistivity electrical properties.

Quartz and macor glass ceramics are better insulators with resistivity values of over 1 10 16. Engineered ceramics tend to have high volume resistivity even at high temperatures although some ceramic materials are engineered purposefully to allow some charge through typically referred to as electrostatic discharge safe or esd safe ceramics lengthening the life of the material or protecting sensitive objects it contacts. Silicon carbide is the least insulating ceramic with resistivity of around 1 10 6 or even less for certain forms of cvd sic. 1 10 10 and zirconia 1 10 9.

Ceramic materials offer a number of benefits in a variety of applications.
