What voltage-withstand capability does the 1 mm thick 96% alumina substrate provide?
The substrate is specified with a breakdown voltage of 15 kV/mm and a nominal thickness of 1 mm, and it is described as an electrical insulating ceramic. Because Atomfair requires confirming thickness tolerance before quotation, verify the actual part dimension before converting the 15 kV/mm specification into an absolute part-level withstand voltage.
Can polishing, coating, metallization, or custom shaping be requested for this 96% alumina substrate?
The product page does not state that these options are automatically included in this standard 160 mm x 160 mm x 1 mm pack-of-10 item. Atomfair's configuration guidance states that polishing, coating, metallization, and custom-shape needs must be confirmed before quotation, so specify the required finishing process when requesting this SKU.
Can this 96% alumina substrate be used in high-temperature or corrosive environments?
The 96% Al2O3 ceramic is described as having a high melting point, good corrosion resistance, chemical stability, and thermal conductivity greater than 24 W/(m·K). The product description does not provide a maximum service temperature or specific chemical exposure limits, so process-specific compatibility should be confirmed with Atomfair before use.
This 96% alumina ceramic substrate (160 mm x 160 mm x 1 mm, pack of 10) offers a balanced set of mechanical, thermal, and electrical properties for laboratory-scale device prototyping or thin-film deposition substrates, with its high flexural strength (>350 MPa) and electrical breakdown voltage (>15 kV/mm) enabling robust handling and insulation under moderate field stress.
Positive
- High mechanical strength and hardness: Flexural strength >350 MPa and Vickers hardness 14 GPa provide structural integrity for machining, clamping, or use as a rigid base layer in high-temperature or high-pressure lab processes.
- Useful thermal conductivity for heat dissipation: Thermal conductivity >24 W/(m·K) enables moderate heat spreading from mounted devices or thin films, reducing localized thermal gradients in prototype or test assemblies.
Trade-offs
- Moderate surface roughness for precision coatings: With Ra 0.15-0.30 µm, the as-fired surface may require additional polishing or planarization for applications demanding ultra-smooth interfaces, such as epitaxial film growth or sensitive dielectric layers.
- Dielectric loss not specified at high frequency: While low dielectric constant and loss are claimed, no numerical values at RF or microwave frequencies are provided, limiting assessment of suitability for high-speed or high-frequency circuit substrates without further characterization.
