Maximum Operating Temperature of advanced ceramics
Advanced ceramics have maximum operating temperature far higher than conventional metals or engineered plastics. In contrast, some high-performance ceramics can withstand sustained operating temperatures up to 2200°C, while conventional metals begin to melt at 1200°C to 1500°C. 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 capable ceramics, such as boron nitride and silicon carbide, require an inert or reducing environment. In an oxidizing environment, their maximum operating temperature may be significantly reduced.
This article explores the maximum operating temperature limits of major ceramic materials, compares them to metals and plastics, and explains how their properties can be exploited in high-temperature applications.
Why High-Temperature Ceramics Matter
Advanced ceramics maintain structural and chemical integrity at extreme temperatures, which is crucial in applications such as:
They offer superior thermal shock resistance, oxidation stability, and low thermal expansion, especially when compared to metals and polymers. This makes them irreplaceable in many high-tech and industrial applications.
What Is the Maximum Operating Temperature?
The maximum operating temperature refers to the highest temperature a material can endure for prolonged periods without experiencing significant degradation in performance, such as softening, melting, oxidation, or structural breakdown.
For ceramics, this temperature is influenced by factors like:
