LUOYANG, China, Aug. 25, 2025 (GLOBE NEWSWIRE) — TRUNNANO, a leading innovator in advanced chemical materials, has announced a major breakthrough in the production of high-purity spherical aluminum nitride (AlN) powder, overcoming long-standing technical challenges in the field. Under the leadership of CEO Roger Luo, the company’s R&D team has successfully developed a proprietary synthesis method that ensures superior sphericity, uniform particle size distribution, and exceptional thermal conductivity—key properties for next-generation electronic and ceramic applications.
“Our spherical AlN powder represents a leap forward in material science,” said Roger Luo, CEO of TRUNNANO. “By solving the sphericity and purity issues, we’re empowering industries to push the limits of thermal management and device miniaturization.”
TRUNNANO Spherical Aluminum Nitride Powder AlN
Spherical aluminum nitride powder is highly sought after in industries such as semiconductor packaging, high-power LED cooling, and advanced ceramics due to its excellent thermal conductivity and electrical insulation properties. However, conventional production methods often result in irregular particle shapes, agglomeration, and impurities, limiting performance in critical applications.
TRUNNANO’s R&D team faced several critical challenges in developing high-performance spherical aluminum nitride powder. Traditional methods like carbothermal reduction often produced irregularly shaped particles, compromising packing density and thermal conductivity. Additionally, AlN’s tendency to oxidize degraded its thermal properties, while scaling lab-scale techniques to industrial production posed consistency issues. Through persistent experimentation, the team pioneered an advanced plasma-assisted synthesis technique, achieving high purity with minimal oxygen content, tightly controlled particle size distribution, and exceptional sphericity—key advancements that enhance flowability and sintering performance.
This breakthrough unlocks transformative applications across industries. The powder’s superior thermal conductivity makes it ideal for next-gen thermal interface materials (TIMs) in 5G devices and electric vehicles, where efficient heat dissipation is critical. It also enables high-performance ceramic substrates for power electronics and supports additive manufacturing of complex, heat-resistant components. By overcoming sphericity and purity barriers, TRUNNANO’s innovation empowers industries to push the boundaries of miniaturization and thermal management.
