What surface finish is supplied on this 96% alumina ceramic substrate, and can it be used as-received for metallization or coating processes?
The as-supplied surface roughness is specified as Ra 0.15–0.30 μm. The product listing requires buyers to confirm polishing, coating, metallization, or custom-shape needs before quoting, so the as-received finish should be validated against your specific deposition or patterning process requirements.
What mechanical strength does the 152 mm x 152 mm x 2 mm 96% alumina substrate provide?
This substrate is specified with flexural strength greater than 350 MPa, Vickers hardness of 14 GPa, and density of 3.70 g/cm³. These mechanical properties, combined with the 2 mm thickness, provide a rigid, hard, dense ceramic plate for laboratory fixtures and structural substrate applications.
What electrical insulation and thermal properties are specified for this 96% alumina ceramic substrate?
The substrate is specified with a breakdown voltage of 15 kV/mm, low dielectric constant, and low dielectric loss. It also provides thermal conductivity greater than 24 W/(m·K), supporting applications where electrical insulation and heat transfer are both required.
This 96% alumina ceramic substrate (152 mm x 152 mm x 2 mm, pack of 10) provides a dense, high-purity Al2O3 surface suitable for demanding laboratory substrate applications, with a flexural strength exceeding 350 MPa and a breakdown voltage of 15 kV/mm. The specified surface roughness of Ra 0.15-0.30 μm and thermal conductivity >24 W/(m·K) make it a viable candidate for thin-film deposition, electrical insulation, and moderate heat-spreading tasks, though its as-fired finish and standard-thickness geometry impose constraints on post-processing and fixturing compatibility.
Positive
- High mechanical and dielectric strength: Flexural strength >350 MPa and Vickers hardness of 14 GPa ensure structural integrity under mechanical and thermal cycling, while a breakdown voltage of 15 kV/mm provides reliable electrical isolation for high-voltage lab setups.
- Good thermal and chemical stability: Thermal conductivity >24 W/(m·K) combined with low dielectric constant and loss supports moderate heat dissipation in RF or power applications, and 96% Al2O3 content confers good corrosion resistance and chemical stability in benign atmospheres.
Trade-offs
- As-fired surface roughness constraints: Surface roughness Ra 0.15-0.30 μm is acceptable for many applications but may require additional polishing or lapping for thin-film adhesion or precision optical bonding, adding post-processing steps.
- Fixed geometry limits fixturing flexibility: The 152 mm x 152 mm x 2 mm dimensions and pack-of-10 format impose size and thickness constraints; custom shaping, metallization, or coating require separate confirmation and may affect lead time or uniformity.
