The maximum operating temperatures of advanced ceramics are much higher than those of conventional metals or engineering plastics. In contrast, some high-performance ceramics can withstand sustained operating temperatures of up to 2,200°C, while conventional metals begin to melt at 1,200°C to 1,500°C. This makes high-temperature ceramic materials ideal for high-temperature industrial applications. This makes high-temperature ceramic materials ideal for high-temperature industrial applications.

However, when selecting materials for use around 2000°C, the application environment must be carefully considered. Many ultra-high temperature ceramics, such as boron nitride and silicon carbide, require inert or reducing environments. In oxidizing environments, their maximum operating temperatures may be significantly lower.

This paper looks at the maximum operating temperature limits of the main ceramic materials, compares them with metals and plastics, and explains how their properties can be utilized in high temperature applications.

The ability of advanced ceramics to maintain structural and chemical integrity at extreme temperatures is critical in the following applications:

They have excellent thermal shock resistance, oxidative stability and low thermal expansion, especially compared to metals and polymers. This makes them irreplaceable in many high-tech and industrial applications.

Maximum working temperature is the highest temperature that a material can withstand for a prolonged period of time without significant degradation of properties such as softening, melting, oxidation or structural damage.

For ceramics, this temperature is influenced by the following factors:
