Ceramic Material Comparison Chart
Thermal conductivity measures how easily heat is transmitted through a material. There is a growing specialist market for advanced ceramics use in applications with high thermal conductivity requirements.
Advanced ceramics have generally low coefficients of thermal expansion which is the measure of how much a material expands due to a rise in temperature. When heat is applied to most materials they expand due to their atomic structure, due to ceramics atomic composition they are able to stay stable across a wider range of temperatures.
