Product Code : CE- Al2O3-4N-Cu
Alumina ceramic cylindrical crucibles (or corundum crucible, aluminum oxide >99%) . Highly resistant to chemical attack. Recommended for chemists, metallurgists and others involved in high temperature work demanding contamination free results. High temperature resistance,1600C in long time use,1800C in short time.
Alumina crucible is a ceramic product with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Alumina has high hardness and good wear resistance, making it a suitable material for ball valves, piston pumps, and deep drawing tools. In addition, it can be easily combined with metals and other ceramic materials using brazing techniques and metalizing. Alumina crucibles can be used under high temperature and do not contaminate most molten metals.
