Frequently Asked Questions

Q1: How does the customisable dimension feature affect integration in assemblies?
A1: Customisable dimensions allow for precise adaptation to unique assembly requirements, reducing gaps and ensuring consistent contact in components. This minimises mechanical stresses and thermal inconsistencies across interfaces.

Q2: What factors should be considered when using this spacer in high-temperature applications?
A2: It is essential to account for thermal conductivity and operating limits. The material’s thermal transfer rate and temperature tolerance help maintain safe and efficient performance, even under continuous high-temperature exposure.

Q3: How are the mechanical properties maintained during production?
A3: The production process uses controlled sintering and meticulous powder processing. In-line SEM inspections and microstructural analyses help maintain target tensile and compressive strengths within defined tolerances.

Additional Information

Alumina-based ceramics have long been utilised in environments demanding high thermal and electrical stability. Their microstructural uniformity, achieved through controlled sintering processes, minimises internal stresses and enhances durability in demanding applications. The chemical inertness of Al2O3 also provides compatibility with various substrates and environments.

Ongoing improvements in ceramic processing techniques continue to refine the performance of alumina products. Advances in quality control methods allow for more accurate predictions of material behaviour under thermal and mechanical loads, enriching their application in both standard and specialised industrial systems.
