Frequently Asked Questions

Q1: What storage conditions are recommended for this alumina crucible?
A1: Store in a dry, temperature-controlled environment away from humidity and sudden thermal shocks. A stable room temperature with low moisture exposure minimises potential micro-cracking and environmental contamination.

Q2: How does the thermal conductivity of 30 W/(m·K) influence processing applications?
A2: The specified thermal conductivity allows for efficient heat transfer within the crucible. This aids in achieving uniform temperature distribution during high-temperature processing, which is crucial for material synthesis and ceramic sintering processes.

Q3: What quality control measures are implemented during production?
A3: Each crucible is subjected to dimensional verification, surface inspection, and mechanical strength tests. These procedures ensure that structural and compositional standards are maintained, reducing the risk of inconsistencies in high-temperature applications.

Additional Information

Alumina, or aluminium oxide (Al₂O₃), is a widely used ceramic material prized for its excellent chemical inertness and electrical insulation properties. Its high melting point and resistance to thermal shock make it suitable for a variety of high-temperature industrial processes. As a structural ceramic, alumina is often selected for applications demanding stability under thermal and mechanical stress. Advances in sintering and surface treatment techniques continue to enhance its overall performance in specialised fields.
