Alumina Ceramic Disc, Aluminium Oxide Disc, Al2O3 Disc 95%, Dia. 76 mm Packing

The disc is individually wrapped in moisture- and anti-static barrier materials and secured in cushioned, rigid containers to minimise mechanical stress during transit. It should be stored in a temperature-controlled, low-humidity environment to preserve material properties. Custom labelling, compartmentalisation, and specialised packaging options are available upon request to meet specific storage and handling requirements.

Frequently Asked Questions

Q1: How does SAM monitor the disc’s microstructure consistency?
A1: SAM employs a controlled sintering process combined with scanning electron microscopy (SEM) analysis to examine the grain structure, ensuring the microstructure remains uniform and porosity is minimised.

Q2: What storage conditions are recommended for these discs?
A2: The discs should be stored in a dry, temperature-controlled environment, protected by anti-static packaging to prevent moisture absorption and particle contamination, which could compromise material properties.

Q3: Is it possible to customise the disc dimensions for specific applications?
A3: Yes, custom dimensional tolerances can be discussed based on application requirements. Customers are advised to provide detailed specifications so that adjustments in the sintering and machining process can be made accordingly.
