Q2: How does the thermal conductivity influence its application in high-temperature processes?
A2: With a thermal conductivity of 30 W/(m·K), the crucible ensures efficient heat distribution, reducing thermal gradients and mitigating the risk of stress-induced defects during prolonged high-temperature operations.

Q3: What recommendations exist for avoiding thermal shock when using the crucible?
A3: It is advisable to gradually ramp up and down the temperature during operational cycles. A controlled heating and cooling profile helps maintain structural integrity and minimises the risk of cracking due to rapid temperature changes.

Additional Information

Alumina (Al2O3) remains a pivotal material in high-temperature applications due to its outstanding chemical inertness and thermal stability. Research into its microstructural behaviour under stress has refined production techniques that optimise its mechanical properties and thermal conductivity, crucial for high-temperature crucible applications.

Understanding the grain boundary characteristics and the impact of minor impurities allows for enhanced control over the material's performance. Continued developments in ceramic processing aim to further exploit alumina's resistance to thermal shock and electrical conduction, thereby expanding its usability in advanced industrial and research applications.
