Frequently Asked Questions

Q1: How does the 99% alumina composition affect thermal stability in high-temperature environments?
A1: The 99% alumina composition minimises impurities, reducing the risk of thermal degradation. This high purity helps maintain stable properties even under prolonged high-temperature exposure, which is crucial for consistent process control.

Q2: What are the recommended temperature cycling practices to avoid thermal shock?
A2: Gradual temperature ramping during heating and controlled cooling cycles are advised to prevent thermal shock. This approach minimises stress buildup in the crucible structure, ensuring prolonged service life and stable performance.

Q3: How should users handle and clean the crucible to maintain its surface integrity?
A3: After use, allow the crucible to cool completely before cleaning. Use non-abrasive cleaning agents and soft tools to remove residues. This procedure prevents surface damage and preserves the material's inherent chemical and physical properties.
