How to use alumina ceramic crucible correctly
In our forging and experiment process, the crucible is a common equipment used. In order to ensure the normal use of the product, it is necessary to master the correct use method. The following is a brief introduction.
Use crucibles when there are solids to be heated with high fire. When the alumina ceramic crucible is used, the crucible cover is usually placed obliquely on the crucible to prevent the heated object from jumping out and allow the air to freely enter and exit for possible oxidation reactions. Because the bottom of the crucible is small, it generally needs to be placed on a mud triangle to be directly heated by fire. The crucible can be placed upright or obliquely on the iron tripod, and can be placed by itself depending on the needs of the experiment.
The alumina ceramic crucible should not be placed on a cold metal table immediately after heating to prevent it from breaking due to rapid cooling. Do not immediately put it on the wooden table to prevent the table from being scalded or cause a fire. The correct way is to leave it on an iron tripod to cool naturally, or put it on an asbestos mesh to cool it slowly. Please use crucible tongs to take the crucible.
