AC9819 Alumina Crucible, Al2O3 Crucible Cylindrical, 95%, 215 mL

Alumina Crucible, Al2O3 Crucible Cylindrical, 95%, 215 mL Description

This Alumina Crucible, chemically denoted as Al₂O₃, features a cylindrical design with a 215 mL capacity. Its formulation at 95% purity, combined with controlled density (3.7-3.9 g/cm³), ensures structural integrity under high stress. With a tensile strength of ~32 Kpsi and compressive strength of ~300 Kpsi, the crucible supports thermal conduction at 25 W/(m·K) and stable operation at temperatures up to 1500 ℃. Additionally, its high volume resistivity (>10^14 Ohm·cm) minimises electrical interference during thermal processing.

Frequently Asked Questions

Q1: How does the microstructural quality of the alumina impact its performance in high-temperature applications?
A1: The microstructure of alumina crucially affects its thermal uniformity and mechanical strength. SAM’s process employs SEM verification to ensure uniform grain distribution, which is essential to sustaining high temperatures without structural degradation or thermal shock.

Q2: What considerations should be taken when using this crucible in industrial processes?
A2: Users should consider pre-heating the crucible to minimise thermal shock, avoid rapid temperature changes during operation, and ensure that loading conditions do not exceed the mechanical limits. These steps optimise its performance under high thermal and mechanical stress.

Q3: Can the crucible be integrated into specialised high-temperature systems without additional modifications?
A3: The crucible’s design supports integration into various high-temperature systems. However, it is recommended to verify compatibility with specific process parameters, such as heating rates and thermal gradients, to fully leverage its material properties.

Additional Information

Alumina, or aluminium oxide (Al₂O₃), is widely recognised for its stability under extreme thermal conditions and excellent insulation capabilities. Its controlled purity and density make it a frequent choice for applications requiring high durability and thermal resistance. Recent advances in sintering technology and microstructural analysis have further enhanced the performance characteristics of alumina components in both industrial and laboratory settings.

Understanding the intrinsic properties of alumina provides a foundation for designing equipment in high-temperature environments. Detailed material characterisation aids engineers in predicting performance outcomes, ensuring that products such as these crucibles meet stringent operational requirements in critical applications.
