Product Description

High Purity Alumina Crucible High Temperature Resistant Ceramic Crucible for Laboratory Sintering and Melting


Alumina ceramic part is produced by firing a tightly packed powder form of Al2O3 which includes some binder material. Commercially available grades range from 90% up to 99.95% with the higher purity generating somewhat higher hardness. Alumina Ceramics are the most highly regarded and widely used of the ceramic products. It is non-conductive, resistant to corrosion,  and are perfect for electrical insulation. Alumina Ceramic has proven to be the best ceramic for protection of vital electrical components. It can be processed as tubing, sheets, bars, rods, discs, and many other forms depending on the requirements of the project. 


Alumina crucible is a high-purity advanced ceramic container specially designed for high-temperature heating, melting, sintering and sample analysis. Made of high-grade alumina powder through isostatic pressing and high-temperature sintering, it delivers excellent structural stability and ultra-high temperature resistance up to 1600°C–1800°C.
This ceramic crucible features outstanding thermal shock resistance, low thermal expansion coefficient and excellent chemical inertness. It resists erosion from most acids, alkalis and molten materials, ensuring no contamination to experimental or industrial samples. Its compact microstructure provides high density, low porosity and superior mechanical strength even under long-term continuous high-temperature operation.
Available in various shapes including cylindrical, conical, square and custom styles, alumina crucibles cover a wide range of capacities and sizes. With precise dimension control and smooth inner and outer surfaces, they are easy to clean and reusable. These crucibles are widely applied in laboratory analysis, material sintering, chemical testing, metallurgical melting, pharmaceutical research and new energy material production.



Alumina Oxide (Al2O3) Properties:
