Frequently Asked Questions

Q1: How does the ≥99% alumina purity influence the disc's performance in high-temperature applications?
A1: The high alumina purity reduces the presence of impurities, which in turn minimises the risk of unwanted chemical reactions and structural degradation. This is essential for components subjected to repeated thermal cycling in industrial environments.

Q2: What measures are taken to confirm the dimensional accuracy of the disc?
A2: Quality control includes high-resolution optical inspections and precise micrometer measurements. These methods ensure that the disc’s 51 mm diameter meets strict dimensional tolerances critical for integration in engineered systems.

Q3: In what way does the density of 3.85 g/cm³ relate to the disc's mechanical performance?
A3: A density of 3.85 g/cm³ indicates a tightly sintered microstructure, which correlates with enhanced resistance to wear and mechanical stress. This property is useful in applications where consistent structural performance is critical under load.

Additional Information

Alumina ceramics, composed primarily of aluminium oxide, exhibit significant thermal stability and chemical inertness due to strong ionic bonds. Controlled sintering processes allow manufacturers to reduce porosity, thereby enhancing mechanical properties and resistance against environmental degradation. These attributes are central aspects when selecting materials for high-temperature and chemically aggressive environments.

Understanding the microstructural dynamics of alumina is essential for predicting its performance in long-term industrial use. Researchers focus on optimising sintering procedures and measuring critical parameters such as density and purity to ensure that alumina-based components reliably meet operational expectations.
