R&D Team
The company enjoys a sound operating environment and employs a high-caliber talent team. It currently has functional departments including the General Operation Department, Technology R&D Department, Production Department, Marketing Department and Finance Department. There are more than 50 professional and technical staff, among whom over 20 are high-end talents with master’s or doctoral degrees. The technical R&D team is built around **Dr. Chen Dongsheng**, an authoritative expert in the industry. His credentials include: Postdoctoral Fellow at Imperial College London, PhD in Biochemistry from the University of Liverpool, Senior Researcher at GSK UK; Yellow River Scholar, Distinguished Professor and Doctoral Supervisor at Henan University; Director of Henan Provincial Engineering Research Center for Inorganic Ion Exchange Resins; and Member of the Expert Committee of the National Strategic Alliance for Technological Innovation of Nickel, Cobalt and Platinum Group Metals Industry.
Manufacturing Capability
At present, the company’s precision alumina ceramic materials are available in four specifications: 175nm, 250nm, 350nm and 500nm. The 175nm grade product shares a similarity of 93% with the 125nm premium grade of Tomei Powder, one of the world’s top-tier products. Moreover, all specifications of our products fully outperform internationally leading benchmark products, including those from Sumitomo (Japan), Martin (Germany), Pechiney (France), Alcoa (the United States), and all Tomei (Japan) products except its 125nm grade. Therefore, the company is fully capable of achieving comprehensive import substitution.
Quality Assurance
The excellent properties of advanced functional ceramics depend largely on the high quality of raw ceramic powders. The preparation of high-quality ceramic powder is the key to obtaining advanced functional ceramics with superior performance. The high-purity low-temperature easily sinterable alumina ceramic powder produced by Tomei Chemical Industry Co., Ltd. of Japan represents the internationally leading level of industrialized alumina ceramic powders, and serves as a critical raw material for manufacturing high-performance civil and military ceramics. In 2020, based on the Torch Program of the Ministry of Science and Technology of China, we broke through the technical bottlenecks of microcrystallization and single-particle dispersion of alumina ceramic powder, and established the foundation for the R&D of industrial production processes for related technologies. Mastering the production processes and core technologies of high-purity low-temperature easily sinterable alumina ceramic powder materials is of great significance for promoting the transformation, upgrading and high-quality development of China’s alumina ceramic industry.
Technical Advantages
The precision alumina ceramic materials produced by Hongcheng boast remarkable professional advantages compared with similar products from world-leading enterprises such as Taimatsu Chemical of Japan.
  • Excellent low-temperature sintering performance
    Hongcheng 175 nm alumina ceramic material achieves a sintered density of 3.93 g/cm³ at 1400°C, requiring only about 50°C higher temperature than Japan’s Tomei Chemical TM‑DAR product, which reaches its sintered density at 1350°C. Hongcheng alumina ceramic materials can realize high‑density sintering at relatively low temperatures, which helps save energy and reduce production costs.
    01
  • Remarkable cost-effectiveness
    Hongcheng alumina ceramic materials are priced at roughly half of those from Tomei Chemical. This cost advantage gives Hongcheng’s alumina ceramic materials greater market competitiveness, making them especially suitable for cost-sensitive application fields.
    02
  • Technology Breakthrough & Independent Innovation
    A scientific and technological novelty search report shows that there is currently no industrialized product of the same type of powder in China. This means that Hongcheng’s alumina ceramic materials have achieved technological breakthroughs, filled the domestic market gap, helped break the monopoly of foreign enterprises, and effectively promoted the upgrading and development of the domestic related industrial chain.
