Product Description
New energy ceramics, particularly advanced ceramic components like silicon nitride (Si₃N₄), play an increasingly vital role in the new energy vehicle sector due to their exceptional comprehensive properties, earning them the title of "King of Structural Ceramics." These critical new energy ceramic components are driving technological advancement across the entire industry.
Key Characteristics
- Mechanical Properties: Exhibits high strength, high hardness (HV ≥ 1450), and low density (approximately 53% of zirconia). This enables it to withstand high stresses while facilitating lightweight component design.
- Thermal Properties: Demonstrate superior high-temperature resistance, enabling all-ceramic bearings to operate stably in lubrication-free environments up to 1200°C. Simultaneously, they serve as excellent thermal conductors, making them critical for manufacturing thermal interface materials in electric vehicle control system chips.
- Chemical & Electrical Properties: Exhibit exceptional corrosion resistance and reliable electrical insulation. Their zero magnetic properties effectively prevent contamination of precision battery materials.

main Application
- Ceramic Substrates for Electronic Control and Thermal Management Systems: Ceramic substrates produced from silicon nitride are primarily used for core chips in smart electric vehicle electronic control systems (e.g., IGBT, SiC modules).
- Bearings: Silicon nitride bearing balls significantly reduce friction losses, increase motor speed and efficiency, and extend service life.
- Battery Production Materials: In lithium battery manufacturing, silicon nitride microbeads are used for ultra-fine grinding of positive and negative electrode materials due to their exceptional wear resistance (10 times more wear-resistant than zirconia beads) and low energy consumption, improving dispersion efficiency by over 30%.
