Product Description
High Thermal Conductivity Green Silicon Carbide
Henan Yumo New Materials develops a high-thermal-conductivity green silicon carbide, a next-generation ceramic engineered to address the thermal limitations faced in contemporary electronics and high-temperature applications. By employing extreme-temperature sintering, precise grain boundary manipulation, and a refined raw material composition, the material enhances the natural heat transfer capability of green silicon carbide, positioning it as a superior solution for heat spreaders, melting vessels, kiln components, and semiconductor components—ensuring stable and dependable performance in high-power systems.
Specification
Core features and advantages | |||
Property | YUMO HC-SiC (High Thermal Conductivity Green SiC) | Regular Reaction-Bonded SiC | Core Value/Benefit |
Ultra-high Thermal Conductivity | ≥ 150 W/(m·K) (at room temperature, up to 270 W/(m·K), comparable to aluminum) | 80 - 120 W/(m·K) | Rapid heat conduction, effectively reducing hot spot temperature and enhancing device performance, reliability, and lifespan. |
High Conductivity & High Strength | Flexural strength ≥ 450 MPa | 300 - 400 MPa | Robust structure, load-bearing and pressure-resistant; suitable as heat dissipation component or structural part under high mechanical loads. |
Excellent Thermal Stability | Low thermal expansion coefficient (4.5×10-6/K); excellent thermal shock resistance | Higher thermal expansion coefficient; average thermal shock resistance | Resistant to rapid cooling/heating without cracking; adapts to frequent start-stop cycles and temperature cycling of power devices. |
High Insulation & Dielectric Properties | Volume resistivity > 10¹² Ω·cm; low dielectric constant | Significant volume resistivity fluctuation | Integrated insulation and heat dissipation; can be directly used as circuit substrate or insulating heat dissipation baseplate, simplifying device structure. |
Lightweight | Density: 3.10 - 3.15 g/cm³ | Density: 3.05 - 3.10 g/cm³ | Much lighter than metal heat dissipation materials like copper and aluminum, facilitating lightweight equipment design. |
Main application areas | ||
Application Area | Typical Product Form | Value Proposition |
Power electronics packaging & thermal management | Heat sink (substrate), thermal slug, insulating frame | Ideal for IGBT, MOSFET, laser diode (LD), and LED assemblies. Superior dielectric properties and heat dissipation effectively substitute alumina (Al2O3) and aluminum nitride (AlN), delivering the best cost-efficiency and markedly lowering junction heat. |
Key consumables for semiconductor manufacturing | Wafer heating disc, paddle, process chamber liner | Acts as essential support material in silicon and SiC semiconductor epitaxial growth, diffusion, and annealing operations. Delivers consistent thermal distribution, withstands elevated temperatures, and prevents wafer surface contamination, thereby maintaining high semiconductor production efficiency. |
High-end specialty smelting & chemical processing | Crucible, boat, guide rail, nozzle | Ideal for refining pure metals, growing crystals like sapphire, and enabling chemical vapor deposition. Its ability to withstand corrosion, resist wear, and transfer heat quickly maintains consistent operation and extends durability. |
High-temperature kilns & energy-saving technology | Kiln furniture (rollers, saggers, burners) | Ideal for processing lithium battery components and manufacturing electronic ceramic parts. Superior heat transfer reduces energy consumption (through quicker temperature changes), robust mechanical properties allow it to support weight without bending, and resistance to thermal stress handles abrupt cooling cycles. |
Advanced lithography & laser systems | Lithography wafer stage, laser mirror substrate | Provides extremely high thermal and dimensional stability, ensuring nanometer-level positioning accuracy and optical precision even under thermal disturbances. |

Technical Implementation: How to Achieve High Thermal Conductivity?
Raw material ultrapurity: Utilizing ultra-high purity submicron silicon carbide powder (>99.95%) significantly reduces phonon scattering centers such as lattice oxygen and metallic impurities.
Advanced sintering methods using pressureless sintering (PLS) or hot isostatic pressing (HIP) yield a finely structured, uniform material approaching theoretical density, leading to clear grain interfaces and minimal phonon scattering.
Through targeted addition of sintering promoters and exact process management, a grain boundary region with superior thermal conduction is developed, leading to enhanced total thermal performance.
Precision machining: Providing end-to-end manufacturing capabilities from raw materials to high-precision finished parts, ensuring low thermal resistance contact during device assembly.
