1. High Thermal Stability: Alumina ceramic crucibles can endure temperatures up to 1800°C, allowing for high-temperature experiments and processes without the risk of melting or thermal degradation. 2. Corrosion Resistance: The inert nature of alumina provides excellent resistance to chemical corrosion, ensuring that the crucibles remain unaffected by acids, alkalis, and other reactive substances commonly used in laboratories. 3. Mechanical Strength: The robust structure of alumina ceramics crucible ensures durability and resistance to mechanical stress, reducing the likelihood of cracking or breaking during handling and use. 4. Purity and Chemical Inertness: With a purity level typically above 99%, alumina ceramic crucibles offer a contaminant-free environment, crucial for precise and accurate chemical analysis.

How to use alumina ceramic crucibles correctly

In our forging and experimental processes, crucibles are commonly used equipment. In order to ensure the normal use of the product, it is necessary to master the correct usage method. Below is a brief introduction.


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.


2. Due to its small bottom, the crucible usually needs to be placed on an iron 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.


3. After heating, do not immediately place the alumina ceramic crucible on a cold metal tabletop to prevent it from cracking due to rapid cooling. It should not be placed immediately on wooden tabletops to prevent scalding or fire. The correct approach is to leave it on an iron tripod for natural cooling, or place it on an asbestos mesh to allow it to cool slowly.


4. Please use crucible pliers for the retrieval of the crucible.
