High Thermal Conductivity Silicon Nitride Ceramic Substrates Boost Heat Dissipation for EVs and IGBT Modules

With the rapid development of electric vehicles (EVs), high-speed rail, and new energy charging systems, thermal management of power devices has become a critical factor in system reliability. The high thermal conductivity silicon nitride (Si₃N₄) ceramic substrate has emerged as a key material for advanced packaging and heat dissipation in third-generation semiconductor devices such as IGBTs, MOSFETs, and SiC modules. Manufactured from high-purity silicon nitride powder, the substrate is sintered at temperatures above 2000°C using a proprietary formula and hot-pressing process. It achieves a thermal conductivity exceeding 80W/(m·K) while maintaining excellent electrical insulation, low dielectric loss, and high mechanical strength. Compared with alumina and aluminum nitride, Si₃N₄ ceramics offer superior toughness and thermal shock resistance, ensuring longer device lifespan and higher system stability. In EV motor drive modules, inverters, DC/DC converters, and fast-charging stations, the Si₃N₄ ceramic substrateeffectively reduces junction temperature and enhances heat dissipation efficiency. Its outstanding fracture toughness and resistance to thermal cycling make it ideal for harsh conditions such as hybrid vehicles and rail transit power systems. Beyond the EV industry, silicon nitride substrates are also used in railway traction systems, power electronic control modules, industrial inverters, and solar inverters. With their combination of high thermal conductivity, electrical insulation, and reliability, Si₃N₄ substrates are redefining the future of power electronics packaging and thermal management.

Low Dielectric Loss and High Strength Silicon Nitride Ceramic Substrates — The Preferred Choice for Next-Generation Semiconductor Packaging

As SiC (silicon carbide) and GaN (gallium nitride) technologies continue to reshape the power electronics industry, the demand for reliable, high-performance packaging materials is increasing. Silicon nitride (Si₃N₄) ceramic substrates, featuring low dielectric loss, high insulation strength, and exceptional mechanical toughness, have become a top choice for advanced power module applications. Made from high-purity Si₃N₄ powder and sintered above 2000°C, the silicon nitride ceramic substrate achieves a dielectric constant below 8 and a loss tangent (tanδ) 80W/m·K) with superior fracture toughness, making them ideal for EV drive systems, railway traction control units, and fast-charging modules. Today, silicon nitride ceramic substrates are widely used in new energy motor control systems, industrial inverters, power conversion modules, and 5G base station amplifiers, providing stable insulation and effective heat dissipation. With their unmatched balance of thermal, electrical, and mechanical performance, Si₃N₄ substrates are redefining the standards of next-generation semiconductor packaging.

Solving High-Speed and Electrical Corrosion Challenges — HIP Silicon Nitride Ceramic Balls Greatly Enhance Bearing Reliability

In EV motors, machine tool spindles, and wind turbine systems, customers face recurring issues with bearing wear and electrical corrosion under high-speed, high-temperature conditions. Traditional steel balls tend to overheat, oxidize, and fail when exposed to stray currents — shortening system lifespan and increasing maintenance costs. To address these challenges, the High-Performance Hot Isostatic Pressed (HIP) Silicon Nitride Ceramic Ball provides a proven solution. Made from ultra-pure Si₃N₄ powder and sintered above 2000°C, the HIP process ensures full density and a pore-free structure, resulting in exceptional toughness and thermal stability. The ceramic ball combines high electrical insulationwith high mechanical strength, preventing electrical pitting and ensuring stable operation even at temperatures up to 1000°C. Weighing only 40% of a steel ball, it reduces rotational inertia and heat generation. Its self-lubricating surface minimizes friction and allows for maintenance-free operation, ideal for long-term reliability in EV motors and precision spindles. Applications include: Dental drill bearings (≈1mm) — ensuring ultra-high-speed stability EV motor bearings (≈10mm) — eliminating electrical erosion Wind turbine generator bearings (≈50mm) — improving durability and safety With advantages of lightweight design, wear resistance, insulation, and long lifespan, HIP silicon nitride ceramic balls are redefining the reliability standard for modern bearing engineering.
