High-purity 99% alumina (Al₂O₃) cylindrical crucibles for ash determination, calcination, and general high-temperature melts up to 1600 °C. 18 stock sizes in cylindrical form, open-top or with lid. Custom sizes and OEM on request.
Why Alumina Crucibles?
Chemical inertness — resistant to most acids, oxides and molten salts (except strong alkalis and hydrofluoric acid)
High-temperature stability — continuous service to ~1600 °C with low deformation
Hard & wear-resistant — high hardness and good dimensional stability after firing
Open-top & with lid — open-top sold per piece, with-lid sets sold per set
Custom sizes — OEM / ODM, custom dimensions and markings available
