What are the electrical insulation and thermal performance specifications of this 96% alumina ceramic substrate?
This 96% Al2O3 ceramic substrate is electrically insulating with a listed breakdown voltage of 15 kV/mm and low dielectric constant and dielectric loss. It also provides useful thermal conductivity of >24 W/(m·K), making it suitable for applications where electrical isolation and heat dissipation are both required in a rigid ceramic plate.
Can this AF-A96-S127P100 96% alumina substrate be polished, coated, metallized, or supplied as a custom shape?
Polishing, coating, metallization, and custom-shape requirements should be confirmed with Atomfair before ordering this substrate. The product page also advises verifying size tolerance, thickness requirement, material grade, surface finish, and package format for the 127 mm x 127 mm x 1 mm, pack-of-10 configuration.
What surface roughness and mechanical strength can be expected from this 1 mm thick alumina substrate?
The substrate has a surface roughness of Ra 0.15–0.30 µm, flexural strength >350 MPa, Vickers hardness 14 GPa, and a density of 3.70 g/cm³. These properties support its description as a white dense ceramic with high mechanical strength, electrical insulation, hardness, and melting point.
This 96% alumina ceramic substrate (127 mm x 127 mm x 1 mm, pack of 10) provides a dense, high-purity Al2O3 body with a flexural strength exceeding 350 MPa and a Vickers hardness of 14 GPa, making it suitable for demanding electrical insulation and structural support in high-temperature laboratory environments.
Positive
- High dielectric breakdown strength: With a breakdown voltage of ≥15 kV/mm, this substrate provides robust electrical insulation for high-voltage or power-electronics applications in lab setups.
- Useful thermal conductivity for ceramics: Thermal conductivity >24 W/(m·K) enables moderate heat dissipation, beneficial for substrates supporting heated samples or power devices in experimental assemblies.
Trade-offs
- Surface roughness tolerance required: The as-fired surface roughness of Ra 0.15–0.30 µm may require additional polishing or planarization for thin-film deposition or precision coating applications.
- Brittle ceramic handling constraints: Despite a flexural strength >350 MPa, the substrate is a brittle ceramic and is vulnerable to edge chipping or fracture if not handled with care or if thermal shock is applied rapidly.
