What are the specified electrical, thermal, and mechanical limits of the ATOMFAIR 50 mm x 50 mm x 2 mm silicon nitride ceramic substrate?
This substrate is specified for use from -55 °C to 850 °C, with thermal conductivity above 60 W/(m·K) and breakdown voltage above 15 kV/mm. Its apparent density is 3.22 g/cm³, flexural strength is above 600 MPa, Young modulus is above 310 GPa, Vickers hardness is above 15 GPa, and fracture toughness is 6.5 MPa·√m.
Can polishing, coating, metallization, or custom-shape processing be applied to the AF-SIN-S050P200 silicon nitride substrate?
Polishing, coating, metallization, or custom-shape needs must be confirmed with Atomfair when required for the application. The product can be produced as tubes, rods, plates, sheets, and custom-shaped ceramic parts, while the selected specification for this item is the 50 mm x 50 mm x 2 mm plate.
What configuration details must be confirmed before quoting the 50 mm x 50 mm x 2 mm silicon nitride substrate?
Before quotation, confirm the Atomfair model AF-SIN-S050P200, selected size of 50 mm x 50 mm x 2 mm, and required quantity. Size tolerance, thickness requirement, material grade, surface finish, and package format should also be verified, and quotation requests should include exact size, thickness, color or package detail, and quantity.
This 50 mm x 50 mm x 2 mm silicon nitride ceramic substrate offers a flexural strength >600 MPa, fracture toughness of 6.5 MPa·√m, and thermal conductivity >60 W/(m·K), making it suitable for high-stress, high-temperature laboratory applications requiring electrical insulation (breakdown voltage >15 kV/mm). Operational constraints include size limitations fixed to the selected specification and potential need for post-processing such as polishing or metallization.
Positive
- High mechanical and thermal durability: Flexural strength >600 MPa and thermal conductivity >60 W/(m·K) provide reliable performance under mechanical stress and thermal cycling from -55 °C to 850 °C.
- Excellent electrical insulation properties: Breakdown voltage >15 kV/mm combined with high insulation resistance supports safe operation in high-voltage ceramic substrate applications.
Trade-offs
- Fixed geometry requires verification: The selected 50 mm x 50 mm x 2 mm specification cannot be altered post-procurement; size tolerance and thickness must be confirmed before ordering to match application fixtures.
- Post-processing may be necessary: Polishing, coating, or metallization are not included by default and must be requested separately, adding lead time and handling complexity for surface-sensitive uses.
