Advantages of Industrial Alumina Ceramic Crucible Cover
The alumina ceramic crucible cover is mainly made of aluminum oxide, which is resistant to high temperatures (1600 ℃ for long-term use and 1800 ℃ for short-term use). When the temperature rises from minus
tens of degrees Celsius to thousands of degrees Celsius in a short period of time, ordinary metal materials often crack or even break due to thermal expansion and contraction. However, alumina ceramics, with their
extremely low coefficient of thermal expansion, can control the volume fluctuations caused by temperature changes within a very small range. It is recommended to increase the temperature rate by 5 ℃/min to
10 ℃/min, and the cooling rate can match the heating rate.
All products through the German DIN standards: DIN43724 / DIN43725 / DIN40680
Applications of Industrial Alumina Ceramic Crucible Cover
1. Melting and casting of metals and alloys
2. Chemical synthesis and processing
3. Materials research and development
4. Quality control and testing in laboratories
5. High-temperature experimentation and analysis
