3. Thermal analysis (e.g., differential thermal analysis, thermogravimetric analysis)
4. Ceramic and glass material processing
5. Chemical decomposition and ashing
6. Pharmaceutical and biochemical research
How to use alumina ceramic crucibles correctly
1.When there is a solid to be heated with high heat, use a crucible. When using alumina ceramic crucibles, the crucible cover is usually placed diagonally on the crucible to prevent heated objects from jumping out and allow air to freely enter and exit for possible oxidation reactions. The crucible, due to its small bottom, usually needs to be placed on a mud triangle to be heated directly by fire. The crucible can be placed directly or diagonally on an iron tripod, and can be placed on its own according to experimental needs.
