UNIQUE FEATURES OF CERAMICS
High Working Temperature
Technical ceramics are able to work under extreme temperatures of over 1000°C which traditional materials such as plastic & metals are not capable of achieving.
Good Mechanical Strength
A large group of technical ceramics are regarded as important structural materials due to their high stiffness and compressive strength compared to metals. Their high strength-to-mass ratio also makes it suitable for light-weight designs.
A large group of technical ceramics are biocompatible, ranging from bioinert ceramics like alumina and zirconia to bioactive ceramics like hydroxyapatite. As a result, it is widely used in implants and biomedical devices.
Technical ceramics are chemically and physically stable even in extreme working conditions. A large group of technical ceramics have excellent resistance to most acids, bases, electrolytes, plasma, and other corrosive media.
Technical ceramics generally have high stiffness and low coefficient because of thermal expansion. It is often used as precision parts, substrates, support for satellite mirror and other components that require high dimension stability and accuracy.
Some technical ceramics like aluminum nitride and aluminum oxide have good heat conductivity. They are often used in cooling systems for high power chips and other applications where heat transfer and electrical insulation are required at the same time.
High Hardness & Water Resistant
Technical ceramics are generally superior in hardness than plastic & metal. It's thus often used as heavy-duty forming tools, tiles for wear protection and ballistic.
Most technical ceramics are good electrical insulators. Typical materials like alumina and zirconia are widely used in high power equipment, electric & electronic devices and other applications where high resistivity is required.
Some technical ceramics are heat insulators. The typical material, zirconia, is widely used for heat insulation and barriers under extreme temperatures.
