Alumina Crucible, Al2O3 Crucible Square, 95%, 40 mL Packing

The crucible is packaged in an anti-static foam-lined container with a rigid cardboard support to prevent mechanical impacts during transit. A sealed plastic bag safeguards the product from moisture and dust. The packaging design considers the material’s sensitivity to contamination, and storage in a dry, cool environment is recommended. Custom labelling and compartmentalised packaging options are available upon request.

Frequently Asked Questions

Q1: How does the crystallographic quality of the alumina influence its performance in high-temperature environments?
A1: The controlled crystalline structure of alumina ensures consistent thermal expansion behaviour and minimises micro-cracking during rapid temperature changes, contributing to stable performance in high-temperature applications.

Q2: What measures are taken to control impurity levels during production?
A2: SAM uses rigorous material sourcing, sintering process controls, and post-sintering inspections including microstructural analysis to reduce impurities, thereby enhancing the product’s operational consistency and chemical inertness.

Q3: Can this crucible be used in reactive environments and what precautions are necessary?
A3: The alumina crucible exhibits chemical inertness that makes it suitable for many reactive environments. However, users should consider pre-testing in specific chemical systems and ensure the crucible is not exposed to extreme thermal shocks to maintain structural integrity.

Additional Information

Alumina ceramics are widely used in environments that demand stable thermal and mechanical properties. The material’s high melting point and chemical inertness make it a staple in laboratory apparatus and industrial processing equipment. Research into sintering methods continues to improve the microstructural uniformity of alumina, which in turn enhances performance reliability.

In the field of advanced ceramics, understanding the interplay between processing conditions and resultant material properties is essential. This knowledge allows engineers to select the appropriate material for specific temperature and stress requirements, ultimately leading to more consistent and reproducible outcomes in both experimental and industrial settings.
