Alumina Classic Crucible - OD 81mm ID 74mm H 107mm

Alumina Classic Crucible is a high-purity aluminum oxide vessel known for its excellent thermal stability, corrosion resistance, and ability to withstand temperatures exceeding 1600 °C without structural degradation. Its inertness to most molten metals, slags, and reactive gases makes it ideal for precise high-temperature experiments and metallurgical processing. Industries such as advanced ceramics, metal casting, and semiconductor manufacturing utilize these crucibles for tasks where purity, thermal endurance, and chemical stability are paramount. Specific applications include alloy melting in research foundries, containment of reactive chemical melts in laboratory synthesis, and calibration of thermocouples in metrology. Research has focused on optimizing sintering parameters for improved density, refining slip casting techniques for dimensional accuracy, and incorporating design modifications such as gas stirring or slag holes for specialized alloy production. In both scientific and industrial settings, Alumina Classic Crucible remains a critical tool for processes demanding consistent high-temperature performance and minimal contamination risk.
