Alumina Crucible Description

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 crucible, tube, and thermocouple sheath forms. 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 at high temperatures and do not contaminate most molten metals.
