What is the thermal conductivity and flexural strength of this 100 mm x 100 mm x 4 mm silicon nitride ceramic substrate, and how do these properties support high-temperature applications?
This silicon nitride substrate has a thermal conductivity above 60 W/(m·K) and a flexural strength exceeding 600 MPa. It is usable from -55°C to 850°C, making it well-suited for demanding thermal and mechanical environments where stable shape retention and high stress resistance are required.
Can this silicon nitride substrate be supplied with custom surface finishes such as polishing, coating, or metallization for integration into specific devices?
Yes, the product description confirms that custom options including polishing, coating, metallization, and custom shapes are available. Customers should specify these requirements during quotation to ensure the substrate meets the exact dimensional, surface, and interface needs of their application.
What are the electrical insulation capabilities of this silicon nitride substrate, and what breakdown voltage can it withstand?
The substrate has a breakdown voltage greater than 15 kV/mm, providing high electrical insulation. This property, combined with its thermal conductivity above 60 W/(m·K), makes it suitable for applications requiring both electrical isolation and efficient thermal management.
This 100 mm x 100 mm x 4 mm silicon nitride ceramic substrate delivers >600 MPa flexural strength, >60 W/(m·K) thermal conductivity, and an operational temperature range of -55 °C to 850 °C, positioning it for high-mechanical-stress and thermal-management applications in laboratory or industrial settings.
Positive
- High mechanical and thermal performance: Flexural strength >600 MPa and thermal conductivity >60 W/(m·K) enable use in applications requiring structural integrity under thermal cycling or high heat loads, such as power electronics substrates.
- Broad operational temperature range: Usable from -55 °C to 850 °C without degradation, supporting both cryogenic and high-temperature processing environments common in advanced ceramic and battery research.
Trade-offs
- Requires confirmation of exact tolerances: Size tolerance, thickness requirement, and surface finish must be verified before ordering, as the substrate's fit for precision fixtures or coating processes depends on these unstated parameters.
- Customization needs separate specification: Polishing, coating, metallization, or custom shaping are not included by default and require additional technical confirmation, adding lead time and requiring prior knowledge of downstream processing steps.
