What is the dielectric breakdown voltage of this 96% alumina ceramic substrate and how does it impact high-voltage applications?
The breakdown voltage is ≥15 kV/mm, meaning a 3 mm thick substrate can withstand at least 45 kV. This high electrical insulation capacity makes it suitable for high-voltage isolation in power electronics and vacuum systems.
Can this substrate be metallized or coated for custom circuit applications?
Yes, metallization and coating options are available upon request. The product description instructs to confirm polishing, coating, metallization, or custom-shape needs with the supplier. The substrate's low dielectric constant and loss further support RF circuit applications.
What storage and handling conditions are recommended for these 96% alumina ceramic substrates to maintain performance?
Store in a clean, dry environment to prevent surface contamination. The substrates have high hardness (14 GPa) and mechanical strength (>350 MPa flexural) but should be handled with care to avoid chipping or scratching, especially on the polished surface (Ra 0.15-0.30 μm).
This 96% alumina ceramic substrate, sized 50 mm x 50 mm x 3 mm, offers a high mechanical flexural strength >350 MPa and a Vickers hardness of 14 GPa, suitable as a rigid insulating platform for thin-film deposition or high-temperature processing, with a thermal conductivity >24 W/(m·K) for moderate heat dissipation.
Positive
- High mechanical strength and hardness: Flexural strength >350 MPa and Vickers hardness of 14 GPa provide robust structural integrity for laboratory fixturing or substrate handling under mechanical stress.
- Useful thermal conductivity for ceramics: Thermal conductivity >24 W/(m·K) aids in dissipating heat from mounted components or processes, exceeding typical electrical-grade ceramics.
Trade-offs
- Moderate surface roughness limits precision coatings: Surface roughness of Ra 0.15-0.30 µm may require additional polishing or planarization before use in applications demanding ultra-smooth interfaces, such as thin-film epitaxy or fine-line metallization.
- Requires verification of size and finish tolerances: The product description mandates confirmation of size tolerance, thickness requirement, and surface finish before procurement, indicating that exact specifications may vary or need custom alignment with lab requirements.
