Everyone understands the importance of innovation and technological independence, but truly tackling this "hard nut to crack" is extremely difficult, as independent research and development has a long cycle and requires significant investment, making it hard to predict whether it will yield the expected returns in the future. However, Jiangxi Yanxun Silicon Materials Co., Ltd., a technology-driven enterprise, has shown unique determination in its investment in independent research and development, demonstrating the "leading goose" effect, setting a benchmark for growing high-tech enterprises, and injecting new momentum into the high-quality development of Jiujiang City in Jiangxi Province.

       Located in the Xinghuo Industrial Park of the Yongxiu Yunshan Economic Development Zone, Jiangxi Yanxun Silicon Materials Co., Ltd. is a subsidiary controlled by Jiangxi Kaimeidi Biomedical Technology Co., Ltd., established in March 2022. It is a high-tech enterprise integrating research and development, production, sales, and services. The company mainly produces a series of organosilicon functional materials, including alcohol-based crosslinking agents, silicone resins, polysilazane, special silicone rubber, and silicone oil. The company has established long-term cooperative relationships with the College of Organosilicon Materials at Jiujiang University, Central South University, and Nanchang Hangkong University. Its main product is a series of polysilazane resin products with an annual output of 21,000 tons, and it has signed cooperation development and supply-demand agreements with several military-civilian joint enterprises.

     "Polysilazane is a type of organosilicon material with unique properties, exhibiting excellent heat resistance, chemical stability, and dielectric performance, showing broad application prospects in fields such as electronic packaging materials, coating materials, and high-performance composite materials. Polysilazane can be prepared into films or coatings through chemical vapor deposition (CVD) or solution processing techniques, and these films and coatings have characteristics such as low dielectric constant and low thermal expansion coefficient, making them suitable for high-frequency electronic devices and microelectronic packaging. With the advancement of electronic technology and the increasing demand for high-performance materials, polysilazane, as a new type of high-performance material, is receiving more and more attention," said Jiang Xiaoping, chairman of Jiangxi Yanxun Silicon Materials Co., Ltd. To break the long-standing situation where polysilazane is dominated by a few foreign companies, the company invested a large amount of manpower and resources from the beginning, collaborating with Tsinghua University, Central South University, and the Organosilicon Industry Research Center at Jiujiang University to conduct systematic research on the synthesis and industrial application of polysilazane. Meanwhile, with the facilitation of relevant government leaders, regulatory authorities, and well-known domestic organosilicon experts from both Fujian and Jiangxi provinces, Jiangxi Yanxun Silicon Materials Co., Ltd. and the Organosilicon Research Center at Jiujiang University jointly funded the establishment of the Jiujiang Silicon New Materials Industry Research Institute, focusing on tackling the synthesis of "bottleneck" materials in the organosilicon industry chain and exploring application scenarios. The original intention of establishing the polysilazane industry-university-research platform is to solve the "bottleneck" problem of key materials and technologies. Through technological breakthroughs in the synthesis and application fields of polysilazane, the goal is to break the monopoly and achieve a strong military and prosperous people. After the unremitting efforts of the R&D team, the challenges of polysilazane synthesis and production technology have finally been resolved, achieving breakthrough results in fields such as military ceramic fibers, aerospace bearing wear-resistant coatings, and high-temperature coatings.

       Planting phoenix trees attracts golden phoenixes. The innovative model of multi-party integration and collaborative development has brought a new development to polysilazane technology in Jiujiang. Jiang Xiaoping told reporters that now, nearly a hundred professionals are engaged in the synthesis and application R&D of polysilazane and other organosilicon materials, including nearly 20 doctors and professors, and over 30 masters, with multiple "organic chemistry laboratory" R&D centers such as the Organosilicon R&D Center at Jiujiang University and the Jiujiang Silicon New Materials Industry Research Institute.

       The company will adhere to the service concept of "Technology knows no boundaries, innovation is limitless," focusing on the industrialization and application research of silicon nitride polymers, taking it as its mission to break foreign technology blockades and overcome "bottleneck" technologies, and revitalizing the national new materials industry. It aims to innovate and create a leading brand in polysilazane, providing leading products, solutions, and technical guidance for customers' innovative needs.

    "In summary, polysilazane, with its unique molecular structure and atomic bond characteristics, shows broad application prospects in various fields, becoming a highly regarded new type of polymer material. The breakthrough in process technology is just the first step in a long journey; product quality is the lifeline of the enterprise. We must further improve the process, ensure quality, and stabilize and mature product quality. At the same time, we need to actively mobilize various resources to focus on how to turn products into commodities and penetrate the market to generate benefits." The employees of Jiangxi Yanxun Silicon Materials Co., Ltd. are full of confidence in the future. With the continuous advancement of technology and in-depth research on polysilazane materials, they believe it will play an increasingly important role in the field of functional materials in the future.
