When exploring the heat resistance of aluminum nitride ceramics and aluminum oxide ceramics, we found that each material has its unique advantages and characteristics🔥买球·(中国)APP官方网站, especially in high-temperature environments.
1、 Heat resistance of aluminum nitride ceramics
Aluminum nitride ceramics (AlN) are highly valued for their excellent heat resistance. Its sublimation decomposition temperature under normal pressure is as high as 2450 ℃, demonstrating its excellent high-temperature stability. The thermal conductivity of aluminum nitride ceramics is as high as 320W/mK, which is close to beryllium (BeO) and silicon carbide (SiC), and several times that of aluminum oxide ceramics. This high thermal conductivity makes aluminum nitride ceramics highly effective when used under extreme high temperature conditions, capable of withstanding temperatures up to 2200 ℃. In addition, aluminum nitride ceramics also have good thermal shock resistance, which makes them less prone to cracking in environments with rapid temperature changes.

Alumina ceramics are also a material with excellent heat resistance, with high heat resistance and extremely low temperature expansion rate, making them very suitable for applications that require precision and consistency. Alumina ceramics have good thermal stability and are not prone to cracking or deformation even with drastic temperature changes. The heat-resistant temperature of alumina ceramics can reach over 1000 ℃, while the heat-resistant temperature of advanced ceramics can reach over 2000 ℃. The characteristics of alumina ceramics make them widely used in high-temperature environments, especially in fields such as aerospace, electronics, and chemical engineering.
Overall, aluminum nitride ceramics have higher temperature resistance limits and better thermal conductivity in terms of heat resistance, making them excellent in applications that require extreme high temperatures and rapid temperature changes. Alumina ceramics, on the other hand, have proven their reliability in high-temperature environments due to their excellent thermal stability and wide range of applications. Therefore🔥买球·(中国)APP官方网站, when choosing heat-resistant materials, it is necessary to decide whether to use aluminum nitride ceramics or aluminum oxide ceramics based on specific application requirements and heat-resistant temperature requirements.
