Alumina Ceramic Ring, Aluminium Oxide Ring, Al2O3 Ring 99%, Dia. 10 mm Packing

Each ceramic ring is individually packaged in a moisture-resistant sealed bag and cushioned with foam inserts within a hard plastic container. This protective packaging minimises mechanical shock and particulate contamination. Storage guidelines recommend a dry, ambient environment to prevent surface degradation. Custom packaging options, including anti-static wrapping and labelled containers, are available to meet specific logistical requirements.

Frequently Asked Questions

Q1: How does the high-purity alumina formulation affect the ring’s performance?
A1: The ≥99% purity in alumina minimises secondary phase inclusions, which reduces potential microcracks and enhances both the mechanical strength and electrical insulation capabilities. This consistency is essential for applications where precise performance under thermal and mechanical loads is required.

Q2: What precautions are recommended during installation of this ceramic ring?
A2: Handle the ring with care to prevent chipping or microfractures. Use appropriate lifting tools and avoid direct contact with hard surfaces. It is advisable to clean the component using non-abrasive methods before installation to avoid contamination that may impair its insulative properties.

Q3: How are key mechanical properties such as tensile and compressive strength verified?
A3: The mechanical properties are validated through standardised testing methods, including tensile and compression tests under controlled conditions. These methods measure the material’s response to stress, ensuring that the ring meets the specified load-bearing criteria for industrial applications.

Additional Information

Alumina ceramics are widely used in engineering applications due to their excellent thermal and chemical stability. The sintering process of Al2O3 involves careful control of temperature and atmosphere, which directly influences the microstructure and, consequently, the mechanical properties of the final component. Understanding the phase composition and grain boundary behaviour is crucial for applications requiring high operational reliability.

The development of alumina-based materials has been driven by the need for components that can withstand aggressive environments. Detailed characterisation techniques such as scanning electron microscopy (SEM) and X-ray diffraction (XRD) provide insights into the material’s crystallographic structure, ensuring that each production batch adheres to rigorous technical standards for consistent performance in industrial settings.
