1. High Thermal Stability: Alumina ceramic crucibles boast remarkable heat resistance, capable of withstanding extreme temperatures encountered during metal melting processes.

2. Chemical Inertness: The inert nature of alumina ensures minimal interaction between the alumina ceramic crucible material and the molten metal, preserving the integrity and purity of the sample being analyzed.

3. Mechanical Strength: Alumina ceramic crucibles exhibit excellent mechanical strength, resisting thermal shock and physical damage during handling and thermal cycling.

4. Uniform Heating: The homogeneous thermal conductivity of alumina ensures uniform heating of the alumina ceramic crucible contents, facilitating even melting and homogenization of the molten metal.

1. Metal Analysis: Alumina ceramic crucibles are widely used in analytical chemistry laboratories for melting and analyzing metal samples, including elemental analysis, alloy characterization, and impurity determination.

2. Material Synthesis: In material science research, alumina ceramic crucibles serve as essential vessels for synthesizing and processing metal-based materials, such as nanoparticles, ceramics, and composites, through controlled melting and solidification processes.

3. Casting and Molding: Industries involved in metal casting and molding utilize alumina ceramic crucibles for melting and pouring molten metals into molds, enabling the production of intricate components with desired shapes and properties.

4. Research and Development: Alumina ceramic crucibles play a crucial role in research and development activities aimed at exploring new metallurgical processes, investigating material properties, and advancing technological innovations in various industries.

 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.
