What breakdown voltage and dielectric performance does this 96% alumina substrate provide?
This 96% Al2O3 ceramic substrate is rated for a breakdown voltage of ≥15 kV/mm and is described as having low dielectric constant and low dielectric loss. Because the rating is expressed per millimeter, the total standoff voltage for the 2 mm plate should be confirmed against your electrode configuration and surface finish rather than assumed from thickness alone.
Can this 50 mm x 50 mm x 2 mm alumina substrate be supplied with polishing, coating, metallization, or custom shapes?
The product documentation lists polishing, coating, metallization, and custom-shape needs as configuration items to be confirmed with the technical sales team, not as standard features of this SKU. To order a modified substrate, specify the exact size, thickness, color or package detail, and quantity, and confirm surface finish, material grade, and package format before quotation.
What surface roughness and mechanical strength values are relevant for mounting this alumina ceramic substrate?
The specified surface roughness is Ra 0.15–0.30 μm, flexural strength is >350 MPa, Vickers hardness is 14 GPa, and density is ≥3.70 g/cm³. These values indicate a dense, hard, mechanically strong ceramic plate, so account for ceramic hardness when selecting machining, drilling, or mounting methods and confirm size and thickness tolerances before ordering.
This 96% alumina ceramic substrate (50 mm x 50 mm x 2 mm, pack of 10) offers a balance of high flexural strength (>350 MPa), electrical insulation (breakdown voltage ≥15 kV/mm), and thermal conductivity (>24 W/(m·K)), making it suitable for laboratory-scale thin-film deposition or electronic substrate testing; however, its as-fired surface roughness (Ra 0.15–0.30 μm) may necessitate post-processing for applications requiring ultra-smooth interfaces.
Positive
- High mechanical and dielectric strength: Flexural strength >350 MPa and breakdown voltage ≥15 kV/mm provide robust structural integrity and reliable electrical isolation in high-voltage or mechanical-load laboratory setups.
- Useful thermal conductivity for dissipation: Thermal conductivity >24 W/(m·K) enables moderate heat spreading from mounted components, reducing localized thermal stress during operation.
Trade-offs
- As-fired surface roughness constraint: Surface roughness of Ra 0.15–0.30 μm is standard for pressed-and-sintered alumina; thin-film metallization or precise bonding may require additional polishing or coating steps to achieve lower roughness.
- Fixed geometry limits application flexibility: Supplied as pre-cut 50 mm x 50 mm x 2 mm substrates; custom shapes, metallization, or polishing require separate processing confirmation, adding lead time and cost.
