Polysilazane: A brilliant new star in the field of new materials

Polysilazane, as an organic polymer containing silicon and nitrogen, is gradually emerging in the field of materials science and has become the focus of attention in many industries. Recently, research achievements and application progress related to polysilazane have been emerging continuously, injecting new vitality into its market development.

1. Outstanding performance and wide application
Polysilazane possesses many unique properties. Its molecular structure is mainly composed of Si-N bonds as the main chain, which endows it with the ability to transform into a ceramic phase (Si₃N₄/SiC) at high temperatures, forming a dense protective layer and thus having excellent high-temperature resistance. In the extreme test of 30 seconds of ablation in an oxygen-acetylene flame at 1500℃, its mass loss was only 0.8%, far superior to that of traditional resin coatings. Meanwhile, after 100 thermal shock cycles (1200℃→ room temperature), there was no cracking, and the strength retention rate was over 90%, demonstrating excellent stability.
With these outstanding properties, polysilazane has been widely applied in multiple fields. In the aerospace field, it is used in the coatings of new-generation rocket engines, protective coatings for satellite solar panels, and thermal barrier systems for hypersonic vehicles. In industries such as high-end semiconductor equipment manufacturing, the demand for it as a coating material is also constantly expanding. In addition, polysilazane is also an important ceramic precursor. With the development of the new materials industry and the growth in demand for ceramic-based materials, its market space is constantly expanding.

2. The market growth momentum is strong
In 2023, the global polysilazane market revenue reached 26.33 million US dollars, and it is projected that this figure will soar to 119.42 million US dollars by 2030, with a compound annual growth rate (CAGR) as high as 19.08% (204-2030). From a regional perspective, the Chinese market has grown rapidly, accounting for 12.81% of the global market share in 2023. It is projected to have a compound annual growth rate of 39.23% over the next six years and reach a scale of 40.06 million US dollars by 2030. The US market also holds a significant position, with a share of 27.28% in 2023 and an expected CAGR of approximately 10.01% in the future. Apart from China, Japan, South Korea, India and Southeast Asia in the Asia-Pacific region will also play an increasingly important role in the polysilazane market. In Europe, Germany is expected to continue maintaining its leading position, with a CAGR of approximately 10.56% from 2024 to 2030.

3. Technological innovation breaks through bottlenecks
For a long time, the preparation process of polysilazane has faced technical bottlenecks, and its relatively active nature makes storage and transportation difficult, which has restricted the expansion of the market scale. However, a series of breakthroughs have been made in recent research and development. For instance, the newly developed catalytic synthesis technology of prepolymers has significantly enhanced the controllability of resin viscosity, meeting various construction requirements such as spraying and impregnation. In the field of wind turbine blade protection, the polysilazane coating does not crack in an alternating environment ranging from -40 ℃ to 120℃. When applied to the inner walls of boilers, it can resist the corrosion of sulfur-containing flue gas and extend the maintenance cycle by more than three times. In addition, the emergence of intelligent coatings with temperature response characteristics prepared through gradient doping technology and environmentally friendly water-based polysilazane coatings has opened up new directions for the application of polysilazane.
Polysilazane has demonstrated great potential in terms of performance, market and technology. With the continuous deepening of research and the continuous expansion of application, it is expected to play a key role in more fields and provide strong support for the development of various industries.
