Frequently Asked Questions

Q1: How does the high alumina purity affect performance in high-temperature applications?
A1: The 99% alumina purity minimises foreign element inclusion, ensuring stable chemical performance and minimal impurity reactions at elevated temperatures. This attribute aids in maintaining the mechanical and thermal integrity required in industrial and laboratory environments, reducing the risk of contamination during repeated heating cycles.

Q2: What precautions are recommended for operating at temperatures close to 1600 ℃?
A2: When operating near the 1600 ℃ limit, it is essential to ensure proper temperature control and gradual heating cycles to prevent thermal shock. Additionally, maintaining an inert or controlled atmosphere minimises adverse reactions. Regular inspection for microfractures is advisable to confirm continued material integrity.

Q3: What measures are taken during the manufacturing process to verify consistency?
A3: The production process includes controlled thermal cycling and microscopic surface evaluation. These steps assess density uniformity and detect any microstructural flaws. Consistency in quality is ensured by adherence to strict process controls and dimensional verification, which are critical for high-temperature applications.
