When heat is applied to most materials they expand due to their atomic structure, ceramics due to their atomic composition are able to stay stable across a wider range of temperatures. Advanced ceramics have half the coefficients of thermal expansion when compared to metals like stainless steel, and this low thermal expansion can be used to advantage on designing assemblies where ceramics can be kept in compression to enhance its mechanical strength.

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.
7.5 [10-6/K]CeramaAlox Ultra Pure is a very high purity (99.95%) grade of Alumina (Aluminum Oxide) exhibiting an exceptional combination of mechanical and electrical properties.Details
4.8 [10-6/K]Shapal Hi-M Soft is a hybrid type of machinable Aluminum Nitride (AlN) ceramic that offers high mechanical strength and thermal conductivity.Details
Advanced ceramics are well known for their heat withstanding properties in which they only start to melt at temperatures around 2000℃. In comparison to more common ceramic materials such as tile or brick, they start to melt at temperatures around 650℃.
9.3 [10-6/K]Macor is a hybrid glass-ceramic with the versatility of a high performance polymer, the machinability of a metal, and the performance of an advanced advanced ceramic. Details
