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.

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.

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

FAQ

Q1.What is alumina crucible?

A1.Crucibles are used in chemistry laboratories as containers for extremely hot chemical compounds and are made from materials with high-temperature resistance. The ceramic form of alumina is commonly used because of its low cost, strength, and ability to withstand temperatures as high as 3272°F (1800°C).

Q2.Is alumina crucible better than graphite?

A2.Alumina crucibles have longer life span compared to clay graphite crucibles, and provide advantage especially for continuous working systems.

Q3.Can alumina crucibles be customized?

A3.Yes.We accept customized alumina crucibles based on drawings.
