Jinbo Shares: Deeply Cultivating High-Purity Aluminum Nitride Powder to Lay the Foundation for High-End Semiconductor Ceramics
From August 26 to 28, 2026, Hunan Jinbo Carbon Co., Ltd. will participate in the 8th Aibang Precision Ceramics Industry Chain Exhibition (Booth No.: Hall 7 - C25). We warmly welcome industry colleagues to visit us and exchange ideas!
01
Company Profile
Since its establishment in 2005, Hunan Jinbo Carbon Co., Ltd. has consistently focused on the R&D, production, and sales of advanced new materials, serving strategic emerging industries such as photovoltaics, semiconductors, lithium batteries, hydrogen energy, and automotive manufacturing.
The company possesses robust independent R&D and continuous innovation capabilities. It has spearheaded numerous major national scientific research projects, including a major special project under the National "863 Program," a key project funded by the Ministry of Science and Technology's Innovation Fund, and a high-tech industrialization demonstration project supported by the National Development and Reform Commission. The company has formulated five industry standards and earned accolades such as "National Key High-Tech Enterprise under the Torch Program" and "National Intellectual Property Demonstration Enterprise." It was also recognized by the Ministry of Industry and Information Technology as one of the first batch of "Little Giant" enterprises (specialized, refined, distinctive, and innovative) and a "Single Champion Enterprise in Manufacturing." Furthermore, it has received the "National May 1st Labor Certificate" and the First Prize of the Hunan Province Science and Technology Progress Award.
The company listed on the Shanghai Stock Exchange’s STAR Market in 2020 and launched a strategy focused on diversified applications and platform-based development. It established industry leadership by pioneering a leap-forward transition—moving from graphite materials to carbon-based composites—for high-end, critical thermal field components in the photovoltaic and semiconductor sectors. In the lithium-ion battery sector, the company developed a series of high-performance thermal field products and established integrated production capabilities covering the entire process for graphite anodes and porous carbon. In the sodium-ion battery sector, its hard carbon anode products lead the industry thanks to advantages such as high purity, high initial coulombic efficiency, high capacity, and high rate performance. In the automotive braking sector, its carbon-ceramic brake friction components meet the needs of various vehicle models, securing the company’s status as a designated supplier for multiple renowned automakers. In the advanced ceramics sector, its aluminum nitride powder products have broken the international monopoly on high-purity, high-thermal-conductivity ceramic materials. Finally, in the hydrogen energy sector, the company has developed high-performance products such as carbon fiber paper and gas diffusion layers, thereby supporting the growth of the hydrogen energy and new energy storage industries.
Centered on the Jinbo Research Institute, the company pools interdisciplinary talent and resources. Committed to independent and original innovation, it conducts in-depth research into high-end new materials and explores cutting-edge technologies across sectors including new energy, semiconductors, automotive, energy storage, robotics, and advanced ceramics, all with the aim of becoming a world-class platform for new material R&D and industrialization.

Key Products
High-purity aluminum nitride (AlN) micron powder, granulated powder, and filler powder.
Breakthroughs in Core Technology:
Achieved an oxygen content of less than 0.85% through precise oxygen impurity control technology. Aluminum nitride ceramic substrates produced using this technology exhibit a thermal conductivity exceeding 230 W/(m·K), reaching the advanced level of similar international materials.
Breakthroughs in Core Equipment:
Independently developed a continuous carbothermal reduction reactor featuring innovative designs for the internal temperature field distribution and atmosphere control system, enabling precise regulation of reaction temperatures and dynamic optimization of the reaction atmosphere.
Breakthroughs in Core Processes:
Established a coupled optimization model for process parameters across the entire workflow, enabling precise control over all key factors—from raw material particle size distribution and carbon-to-aluminum molar ratios to sintering protocols—while utilizing proprietary surface modification technology to resolve technical challenges such as the material's susceptibility to hydrolysis.
Jinbo’s facility for the annual production of 500 tons of high-purity, high-thermal-conductivity aluminum nitride powder is set to commence operations in late August. Details regarding the relevant technology and production capacity planning will be presented at the "Ceramic Substrate and Power Semiconductor Forum," held concurrently with the exhibition. Speaker: Feng Guoli, Marketing Director at Jinbo. Time/Location: August 26, 16:20–16:40, Forum Area 3, Hall 7, International Convention and Exhibition Center. We look forward to welcoming you there for an exchange of ideas!
