Specifications of High Thermal Conductivity Si3N4 Silicon Nitride Ceramic Block/Plate/Part

High Thermal Conductivity Si3N4 Silicon Nitride Ceramic Blocks/Plates/Parts are engineered for demanding applications requiring efficient heat management. This advanced ceramic material combines exceptional thermal conductivity with strong mechanical properties. The thermal conductivity of Si3N4 reaches approximately 90 W/m·K, outperforming many traditional ceramics like alumina. This makes it ideal for heat dissipation in high-power electronics, LED modules, and semiconductor equipment.

The material maintains structural stability under extreme temperatures. It operates reliably in environments up to 1000°C in oxidizing conditions. In inert atmospheres, it withstands temperatures exceeding 1300°C. Its low thermal expansion coefficient minimizes shape distortion during rapid temperature changes. This reduces stress fractures in applications like furnace components or aerospace parts.

Mechanical strength is a key advantage. Silicon nitride offers high fracture toughness, typically 6-7 MPa·m¹/². This resists chipping or cracking under mechanical load. It also demonstrates excellent wear resistance, extending service life in abrasive settings. Compared to metals, it reduces weight while maintaining durability, suitable for automotive or industrial machinery.

Electrical insulation properties ensure safety in high-voltage applications. The material prevents current leakage even at elevated temperatures. This is critical for substrates in power electronics or insulating components in energy systems.

Customization options include precise dimensions and surface finishes. Standard thickness ranges from 0.5 mm to 50 mm. Tolerances as tight as ±0.01 mm are achievable for specialized uses. Surface roughness can be polished to Ra ≤0.1 µm for smooth contact in thermal interfaces.

Chemical resistance enhances versatility. Si3N4 resists corrosion from acids, alkalis, and molten metals. This suits harsh industrial environments like chemical processing or metallurgy.

Certifications comply with international standards, including ISO 9001 and RoHS. Material purity exceeds 99%, ensuring consistent performance. Testing data for density (3.2-3.3 g/cm³) and hardness (HRA 92-94) is available upon request.

Packaging uses anti-static materials to prevent contamination during shipping. Custom protective solutions are available for fragile or high-precision parts. Technical support assists with design optimization for specific thermal or mechanical requirements.

5 FAQs of High Thermal Conductivity Si3N4 Silicon Nitride Ceramic Block/Plate/Part

What is high thermal conductivity Si3N4 silicon nitride ceramic? Si3N4 ceramic is a advanced material made from silicon and nitrogen. It is produced through a high-temperature sintering process. This ceramic has strong mechanical strength, excellent thermal stability, and resists wear and corrosion. Its high thermal conductivity makes it ideal for heat management in demanding environments.

Why does silicon nitride ceramic have high thermal conductivity? The atomic structure of Si3N4 allows efficient heat transfer. Unlike traditional ceramics like alumina, silicon nitride has fewer impurities and a dense microstructure. This reduces heat resistance. Its thermal conductivity ranges between 20-30 W/m·K. This is higher than most ceramics but lower than metals like aluminum.

Where is high thermal conductivity Si3N4 ceramic used? It is common in industries needing heat dissipation and durability. Examples include semiconductor manufacturing, LED lighting, and power electronics. It is used for substrates, heat sinks, and insulating parts. Aerospace and automotive sectors use it for engine components and sensors.

What temperature can Si3N4 ceramic handle? It operates reliably from -200°C to 1200°C. It withstands rapid temperature changes without cracking. This thermal shock resistance comes from its low thermal expansion. It stays stable in extreme heat, making it suitable for furnaces and high-speed machining tools.

Why choose Si3N4 ceramic over metals or other ceramics? Metals conduct heat better but corrode or oxidize at high temperatures. Silicon nitride resists oxidation and chemical attack. It is lighter than steel and maintains strength in harsh conditions. Unlike metals, it is electrically insulating. This prevents short circuits in electronic applications. Its durability reduces replacement costs.
