Ceramic materials are known for their ability to withstand high temperatures.
Even everyday ceramic items like tiles and bricks can handle very high temperatures.
Technical ceramics are specially made to be extremely heat-resistant, making them ideal for high-temperature environments.
5 Key Points to Know About Ceramic and High Temperatures
1. Pre-Processing Steps
Ceramic components go through several pre-processing steps to refine and shape the material before being exposed to high temperatures.
2. Temperature Tolerance
Some advanced ceramics can be heated to temperatures as high as 3,100°F (1,700°C) and beyond.
These ceramics are used in various applications, including tableware, cookware, wall tiles, sanitaryware, structural ceramics like bricks and roof tiles, refractories, and metal crucibles.
3. High-Temperature Applications
One example of high-temperature ceramic applications is in dental implants.
Ceramic composites are extruded and cut into various shapes, then heated in a highly uniform furnace to prevent shrinkage or distortion.
Remotely controlled undersea cameras and other manned devices also use technical ceramics that require high-fire furnaces.
High-temperature ceramics can also be used in buoyancy devices, where alumina spheres are heated to 3,000°F (1,650°C) and bonded together.
4. Traditional Uses
Traditional ceramics have been used for centuries in products like cooking vessels, serving dishes, and sculpted figures.
Clay mixed with various materials can be formed into the desired shape and then hardened in a high-temperature kiln or furnace.
5. Challenges in High-Temperature Applications
While ceramic material production generally requires sintering at temperatures over 1000°C, integrating metals, glass, and polymers with low melting points with functional ceramics becomes challenging.
High-temperature film applications may lead to crack formations and substrate-coating incompatibilities and discontinuities, as well as longer processing times.
These factors can adversely affect the optical, electrical, and mechanical properties of the ceramic device or decrease its performance.
