What electrical insulation and heat-dissipation performance does this 96% alumina ceramic substrate provide?
This 96% Al2O3 substrate is specified with a breakdown voltage of 15 kV/mm and thermal conductivity greater than 24 W/(m·K), while maintaining a low dielectric constant and low dielectric loss. It is therefore suited to applications requiring electrical insulation combined with useful heat transfer through the ceramic body.
Is this 13.5 mm x 13.5 mm x 1 mm substrate supplied ready for metallization, polishing, or coating?
The listed product is supplied as a 96% alumina technical ceramic substrate with a white dense appearance and a surface roughness of Ra 0.15–0.30 µm; the product description does not state that metallization, polishing, or coating is included. Buyers should confirm these options separately before quotation because custom surface finishing requirements are not automatically matched.
What mechanical strength should be expected when handling or mounting this alumina substrate?
The material is specified with a flexural strength above 350 MPa, a Vickers hardness of 14 GPa, and a density of 3.70 g/cm³. The product description does not provide separate handling or storage instructions, so these mechanical values should be used when evaluating fixturing, packaging, and mounting approaches for the ceramic plate.
This 96% alumina ceramic substrate (13.5 mm x 13.5 mm x 1 mm, pack of 50) provides high mechanical strength (>350 MPa flexural) and electrical insulation (≥15 kV/mm breakdown voltage) suitable for demanding lab applications, though its surface roughness (Ra 0.15–0.30 μm) and moderate thermal conductivity (>24 W/m·K) impose processing and thermal management trade-offs.
Positive
- High mechanical and insulating strength: Flexural strength >350 MPa and breakdown voltage ≥15 kV/mm support reliable performance in structural and high-voltage isolation applications.
- Good corrosion and chemical stability: 96% Al2O3 composition resists many corrosive environments, enhancing durability in chemical processing or harsh lab settings.
Trade-offs
- Surface roughness limits precision bonding: As-fired surface roughness Ra 0.15–0.30 μm may require polishing for thin-film deposition or tight-tolerance metallization, adding processing steps.
- Moderate thermal conductivity constrains dissipation: Thermal conductivity >24 W/m·K is lower than advanced ceramics like AlN or BeO, limiting heat-spreading capability in high-power-density designs.
