Aluminium oxide Crucible
My factory looking for distributors.
Advantage of Aluminium oxide crucible
1. The Aluminium oxide crucible has a relatively high thermal conductivity, which enables it to rapidly conduct and disperse heat, making the temperature distribution more uniform during the smelting process.
2. The Aluminium oxide crucible has an extremely low coefficient of thermal expansion, and it is not prone to cracking or deformation when the temperature changes drastically.
3. Compared with traditional graphite or metal crucibles, the Aluminium oxide crucible is lighter in weight, making it easier to handle and quickly place in and take out of a high-temperature furnace.
Application of Aluminium oxide crucible
1. The Aluminium oxide crucible is suitable for smelting high-melting-point metals such as steel, iron, copper and their alloys.
2. The high thermal and chemical stability of the Aluminium oxide crucible ensures the purity of the alloy composition, avoids interference from impurities, and improves the consistency of product performance.
3. The Aluminium oxide crucible is used in high-temperature synthesis and pyrolysis experiments, providing a stable container for studying the properties of metals.
