What mechanical and electrical properties does the 96% alumina ceramic substrate provide?
The 96% alumina (Al2O3) substrate provides high mechanical strength, electrical insulation, hardness, and melting point. For the 100 mm x 100 mm x 3 mm specification, the stated properties are density ≥3.70 g/cm³, flexural strength >350 MPa, Vickers hardness 14 GPa, breakdown voltage ≥15 kV/mm, and thermal conductivity >24 W/(m·K), with a low dielectric constant and low dielectric loss.
Can this 96% alumina substrate be supplied with custom surface finishing, metallization, or coating?
The substrate is supplied with a white dense ceramic appearance and surface roughness Ra 0.15-0.30 µm. If polishing, coating, metallization, or custom-shape processing is required, those options must be confirmed with the technical sales team before quotation because the standard selected specification is delivered as an independent 100 mm x 100 mm x 3 mm item.
What procurement details should be verified before ordering the 100 mm x 100 mm x 3 mm alumina substrate pack?
Confirm the Atomfair model AF-A96-S100P300, 100 mm x 100 mm x 3 mm dimensions, pack of 10, and required quantity before quotation. Size tolerance, thickness requirement, material grade, surface finish, and package format should also be verified, and any polishing, coating, metallization, or custom-shape needs should be stated when requesting support.
This 96% alumina ceramic substrate (100 mm x 100 mm x 3 mm) offers a flexural strength >350 MPa, Vickers hardness of 14 GPa, and thermal conductivity >24 W/(m·K), making it suitable for high-temperature, electrically insulating mechanical supports in laboratory or thin-film processing environments. The Ra 0.15–0.30 μm surface finish and breakdown voltage ≥15 kV/mm define its compatibility with metallization or dielectric layer deposition, though the relatively low thermal conductivity relative to higher-purity alumina grades may limit heat-spreading performance in high-power density applications.
Positive
- High mechanical and dielectric strength: Flexural strength >350 MPa and breakdown voltage ≥15 kV/mm provide robust structural integrity and electrical isolation for demanding lab fixtures or substrate carriers.
- Controlled surface roughness for processing: Surface roughness Ra 0.15–0.30 μm is specified, enabling consistent contact for thin-film coating, screen printing, or metallization without requiring additional polishing in many standard applications.
Trade-offs
- Moderate thermal conductivity for 96% alumina: Thermal conductivity >24 W/(m·K) is adequate for general insulation but lower than 99%+ alumina substrates (>30 W/(m·K)), requiring careful thermal management in high-power or rapid-cycling tests.
- Brittle ceramic requires careful handling: As a dense ceramic with Vickers hardness 14 GPa, the substrate is susceptible to chipping or cracking under point loads or thermal shock, necessitating proper fixturing and controlled heating/cooling rates.
