Alumina Crucible Boat
Advantages of Alumina Crucibles Boats
1. High temperature resistance:1600℃ in long use,1800℃ in short use. This makes it an ideal solution for various thermal processing applications.
2. Excellent thermal shock resistance: Alumina crucibles boat have excellent thermal shock resistance, which means they can withstand rapid changes in temperature without cracking or breaking.
3. Non-reactive: Alumina crucibles boat are non-reactive, which means they won't react with the substances being heated, melted or cast inside them, ensuring the purity of the final product.
4. Corrosion and Chemical Resistance: The ceramic material used in the alumina crucible boat exhibits excellent chemical resistance and resistance to corrosion. As a result, it can handle harsh chemicals and acids that might otherwise damage other materials.
5. Minimal Thermal Expansion: The alumina crucible boat has minimal thermal expansion, which means that it will maintain its shape and size at high temperatures, avoiding any potential risks of.
Applications of Alumina Crucible Boats
1. Alumina crucible boats are used as containers for analyzing and firing materials and products in various industries.
2. Alumina crucible boats are used for coal analysis, metal analysis and melting, chemical material analysis and firing, glass analysis and melting.
3. The alumina crucible boat is used for the analysis and firing of rare earth and other raw materials and minerals.
4. Alumina crucible boats are used in industries such as the firing of high-temperature ceramic lamps and the melting of single crystal raw materials.
