What is the maximum temperature for alumina ceramic?

Alumina ceramics can withstand temperatures between 1400°C and 1800°C, making them highly versatile for high-temperature applications. Magnesium aluminate has a maximum use temperature of 1700°C, offering excellent thermal stability. Porous alumina can be used in a range from 500°C to 1700°C, suitable for lightweight applications requiring thermal resistance. Lastly, porous aluminium silicate is effective at temperatures between 1350°C and 1650°C. These ceramics are chosen based on their ability to maintain integrity and performance in high-temperature environments, particularly when oxidation is minimized.

Key Points:

• Alumina: Known for its versatility and high-temperature stability.
• Magnesium Aluminate: Offers excellent thermal stability at even higher temperatures.
• Porous Alumina: Suitable for applications requiring lightweight and thermal resistance, with a broad temperature range.
• Porous Aluminium Silicate: Provides good thermal properties for various applications.

These temperatures indicate the ceramics' capabilities in inert atmospheres, where oxidation and other reactions are minimized.
