Alumina Ceramic Disc, Aluminium Oxide Disc, Al2O3 Disc 99.5%, Dia. 32 mm Packing

The discs are individually packaged in protective anti-static pouches and secured within foam-lined boxes to prevent physical damage and contamination. Storage instructions recommend a dry, temperature-controlled environment to maintain material characteristics. Custom packaging options, including specialised cushioning and labelling, are offered to accommodate specific handling requirements.

Frequently Asked Questions

Q1: How does the high purity of the alumina disc affect its performance?
A1: The high purity (≥99.5%) minimises impurity-induced defects, enhancing electrical insulation and mechanical robustness. This ensures consistent performance, particularly in applications where material stability and chemical inertness are critical.

Q2: What storage conditions are recommended for maintaining the disc’s integrity?
A2: It is advised to store the discs in a controlled, dry environment with stable temperatures. Such storage minimises moisture absorption and thermal stress, thus preserving the disc’s physical and chemical properties.

Q3: Can the disc dimensions or material properties be customised for specific applications?
A3: While the standard product features a 32 mm diameter and fixed composition, customisation may be available based on specific tolerance and material property requirements. Consultation with technical support is recommended for detailed customisation options.

Additional Information

Alumina ceramics are widely recognised for their excellent chemical inertness and hardness. The material’s crystalline structure contributes to high resistance against mechanical wear and high operating temperatures, making it a frequent choice in industrial and electronic applications. Advances in sintering technology have allowed for tighter control over grain size and density, which directly impacts performance in precision components.

These ceramics are integral to applications requiring stable dielectric properties and dimensional accuracy. Their role in insulating and structural components in electronics and heavy machinery reflects ongoing improvements in materials processing and quality assurance techniques within the ceramics industry.
