Alumina ceramic crucibles, usually, we call crucibles with more than 95% alumina content as corundum crucibles. Alumina ceramic crucibles and corundum ceramic crucibles include: arc alumina crucibles, square alumina crucibles, rectangular alumina ceramics crucibles, cylindrical ceramic crucibles, and various special-shaped alumina ceramics crucibles.
Corundum ceramic crucible series: suitable for various laboratory metal and non-metal sample analysis, and various industrial analysis.
At present, our factory’s alumina crucibles with a capacity of 50KG-1000KG are all made in the form of pouring. The main material of the corundum crucible is neutral refractory corundum mullite. The corundum crucible is usually used at a temperature of 1600 degrees.
