Alumina ceramic crucible for melting metal in laboratory

My factory looking for distributors.

1. The alumina ceramic crucible is carefully crafted from high-purity alumina raw materials and has remarkable high-temperature resistance characteristics.

2. The chemical properties of alumina ceramic crucible are extremely stable and almost do not react with common chemical substances. Ordinary crucibles are likely to undergo chemical reactions with these substances.

3. Even in high-temperature environments, alumina ceramic crucible can still maintain high mechanical strength.

4. Compared to some crucibles with higher thermal conductivity, choosing alumina ceramic crucible can reduce energy consumption, save energy costs, and help maintain a constant internal temperature of the crucible.

5. The raw materials used to manufacture alumina ceramic crucibles have extremely high purity and do not introduce any impurities into the melted material during the melting process.

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.

• Slip casting moulding: Inject the prepared slurry into the gypsum mold and let it stand for a period of time to allow the gypsum mold to absorb moisture. The slurry forms a uniform body on the inner wall of the mold.

• Injection moulding: Inject a slurry containing paraffin into a metal mold at a certain temperature and pressure, and after the body cools and solidifies, perform demolding to prepare ceramic bodies.

• Extrusion moulding: Suitable for long tube products, the powder is extruded into shape through an extruder.

Q1.Why alumina ceramic crucible is used?

A1.Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures. Used as a protector for high-temperature thermal couples. Used as a material for the chemical industry due to its high corrosion resistance.

Q2.What is the use of ceramic crucible?

A2. Alumina ceramic crucibles are crucial pieces of chemical equipment used for melting down materials, an effective way to reuse scrap items.Ceramic crucibles make it easier to recycle metallic materials because they can easily be cast into new objects or combined into new alloys.

Q3.What is an alumina ceramic crucible made of?

A3. 99.3% Al2O3 Crucibles

Sintered alumina ceramic curcibles ideal for very high temperature applications up to 1700°C. It is resistant to chemical attacks from most acids and alkaline solutions as well as hydrogen and other reducing gases, with the exception of : High concentration hydrofluoric acid.
