What flexural strength and thermal conductivity does the 96% alumina ceramic substrate provide, and how do these properties influence its reliability in high-temperature or high-vacuum applications?
The substrate offers flexural strength >350 MPa and thermal conductivity >24 W/(m·K). These values ensure mechanical robustness under thermal cycling and moderate heat spreading, making it suitable for high-vacuum feedthroughs, heater platforms, and plasma chamber components where both structural integrity and thermal management are critical.
What surface roughness and dielectric performance make the 96% alumina substrate compatible with thin-film metallization or thick-film printing processes?
The surface roughness is Ra 0.15–0.30 µm, which provides adequate adhesion for thin-film deposition without requiring extensive polishing. Combined with low dielectric constant and low dielectric loss, the substrate minimizes signal attenuation at RF and microwave frequencies, supporting applications such as hybrid microcircuits, antenna substrates, and power module isolation layers.
What mechanical and electrical specifications should be considered when integrating the 1.5 mm thick 96% alumina substrate into a high-voltage or multilayer assembly?
The substrate has a Vickers hardness of 14 GPa and flexural strength >350 MPa, indicating high hardness but brittleness — edge chamfering and careful handling are recommended to prevent chipping. The breakdown voltage is ≥15 kV/mm, so for a 1.5 mm thickness the theoretical insulation capability exceeds 22.5 kV, making it suitable for high-voltage isolation in power electronics, X-ray sources, and capacitor stacks.
This 96% alumina ceramic substrate (125 mm x 125 mm x 1.5 mm, pack of 10) offers high flexural strength (>350 MPa), thermal conductivity (>24 W/(m·K)), and electrical insulation (breakdown voltage ≥15 kV/mm), making it suitable for demanding laboratory and industrial applications requiring mechanical robustness and dielectric performance.
Positive
- High mechanical and thermal performance: Flexural strength >350 MPa and thermal conductivity >24 W/(m·K) provide structural integrity and heat dissipation for high-power or high-temperature setups.
- Excellent electrical insulation and stability: Breakdown voltage ≥15 kV/mm, low dielectric constant/loss, and good corrosion resistance ensure reliable electrical isolation and chemical durability in aggressive environments.
Trade-offs
- Surface roughness requires verification: As-fired surface roughness Ra 0.15–0.30 µm may necessitate additional polishing or coating for applications demanding ultra-smooth interfaces or precise metallization.
- Size tolerance and configuration must be confirmed: The product is supplied as a selected specification; buyers must verify exact size tolerance, thickness, and surface finish requirements before ordering to avoid dimensional mismatch.
