The domestic polysilazane industry chain is steadily advancing, and multiple sectors are accelerating the independent control of high-end materials.

1. The strategic value of high-end ceramic precursor materials is prominent.
Polysilazane, as the core precursor of polymer-derived ceramics, is a key basic material in the high-end manufacturing field. After heat treatment, it can be transformed into high-performance ceramics, which can be made into coatings, adhesives, preformed bodies, and other forms, covering semiconductor, aerospace, energy chemical, and high-end equipment, among other key sectors. In the past, high-end products were long monopolized by overseas technologies, and the material supply restricted the progress of many domestic high-end projects. Achieving the autonomy of polysilazane is of great practical significance for the security of the new material industry chain.

2. Domestic synthesis and purification processes continue to make breakthroughs.
The domestic research and industrial sectors have been continuously working on synthesis routes and purification refining processes, gradually optimizing the means of molecular structure regulation, and continuously improving product nitrogen content, ceramic conversion rate, and batch stability. Some indicators have already approached the advanced international level. Based on the stable production of anti-corrosion grade products, the industry is continuously advancing towards the direction of ultra-high purity electronic grade, solving technical difficulties such as impurity control and precise viscosity regulation, and gradually narrowing the supply gap of high-end products. The domesticization level of key upstream raw materials has been improved, laying the foundation for the release of polysilazane production capacity.

3. Diversified downstream demands drive the continuous growth of market size.
Coating is the main application direction of polysilazane, and the demand for chemical heavy anti-corrosion and high-temperature equipment protection is continuously rising. In the semiconductor field, it is used for dielectric films and packaging interface layers, and strict requirements are placed on material purity. In aerospace thermal protection and new energy storage fire-resistant materials, new markets are brought. The overall industry maintains a high growth rate, and the downstream market gradually penetrates from military high-end scenarios to civilian industrial fields. The market demand continues to expand, forcing the construction of production capacity and product iteration upgrades.


4. Future development focuses on process optimization and scenario certification.
At present, the industry development not only needs to overcome synthesis technology but also needs to complete a large number of downstream working condition validations and engineeringization certifications. The future development focus is on: promoting stable production of hundreds of tons or more, improving the product standardization system; developing UV curing, water-based environmentally friendly and other new products; developing customized solutions for different industries and completing more practical validations in industrial scenarios. With the continuous maturation of technology, polysilazane is expected to continuously expand the market share of domestic substitution, enabling the upgrading of domestic high-end manufacturing.
