What are the specified electrical, thermal, and mechanical properties of this 96% alumina ceramic substrate?
This 96% Al2O3 substrate has a flexural strength greater than 350 MPa, a Vickers hardness of 14 GPa, a breakdown voltage of at least 15 kV/mm, and a thermal conductivity greater than 24 W/(m·K). Its density is at least 3.70 g/cm³ and its surface roughness is Ra 0.15-0.30 µm. The material is also described as having low dielectric constant and dielectric loss.
Does this 96% alumina ceramic substrate provide corrosion resistance and chemical stability for demanding environments?
Yes, the 96% Al2O3 material is described as having good corrosion resistance, chemical stability, and a high melting point. The substrate is specified with a white dense ceramic appearance, but no specific chemical exposure limits or maximum service temperature are listed in the product data, so application-specific compatibility should be confirmed with Atomfair technical sales.
Can this 18 mm x 18 mm x 1 mm substrate be supplied with polishing, coating, metallization, or custom shapes?
Polishing, coating, metallization, and custom-shape needs can be included for this substrate, but they must be confirmed with Atomfair technical sales when required for the application. The standard selected specification is 18 mm x 18 mm x 1 mm in a pack of 50, and size tolerance, thickness, material grade, and surface finish should be verified before quotation. Contact inquiry@atomfair.com for configuration support.
This 96% alumina ceramic substrate (18 mm x 18 mm x 1 mm, pack of 50) combines high mechanical strength (>350 MPa flexural), electrical insulation (>15 kV/mm breakdown voltage), and useful thermal conductivity (>24 W/m·K) with a dense white sintered structure, making it suitable for laboratory benchwork and high-temperature test fixtures requiring dimensional stability at reasonable cost.
Positive
- Robust mechanical and thermal performance: Flexural strength >350 MPa and thermal conductivity >24 W/m·K enable the substrate to withstand moderate thermal cycling and mechanical loading in lab jigs or electrical test fixtures without cracking or overheating.
- High electrical insulation reliability: Breakdown voltage =15 kV/mm ensures effective electrical isolation for high-bias or discharge-sensitive experiments, reducing leakage risk in electrochemical or semiconductor test setups.
Trade-offs
- Surface roughness requires process verification: Ra 0.15–0.30 µm may necessitate polishing or post-processing for applications demanding ultra-flat surfaces (e.g., thin-film deposition), introducing additional handling steps and cost.
- Fixed dimension limits application flexibility: Supplied only as 18 mm x 18 mm x 1 mm plates; users requiring custom shapes, holes, or metallization must confirm feasibility separately, potentially delaying procurement.
