I. Technological Breakthroughs Drive Continuous Expansion of Application Scenarios
As an organic-inorganic hybrid material, polysilazane's core advantage lies in its high-temperature ceramic conversion characteristics. With optimized synthesis processes, its pyrolysis ceramic yield has exceeded 85%, far surpassing traditional polycarbosilane. This characteristic enables its breakthrough application in the semiconductor packaging field: as a low-k dielectric constant material, it can meet the requirements of thermal expansion coefficient matching for packaging materials in chips below 5nm. Domestic companies have achieved large-scale mass production of hexamethylcyclotrisilazane, with a product purity of 99.999% and metal impurities controlled below 1ppb, successfully entering the supply chains of leading companies such as SMIC and Yangtze Memory Technologies.

In the new energy field, polysilazane, as a binder for the negative electrode of lithium-ion batteries, can improve battery cycle life by more than 30%. Its derived solid electrolyte coating technology reduces the interface impedance of solid-state batteries to below 10Ω·cm², accelerating the industrialization of solid-state batteries.

II. Explosive Market Demand Spurs a New Industrial Landscape
The global polysilazane market is projected to grow at a CAGR of 19.08%, reaching $119 million by 2030. China, as the largest growth engine, will see demand exceed 2,600 tons, with electronic-grade products accounting for over 35%. Downstream applications are diversifying: semiconductor packaging accounts for 45%, new energy batteries 25%, and aerospace high-temperature coatings 15%, forming a three-way competitive landscape.

Domestic companies are achieving leapfrog development through "technology iteration + cost optimization." Green synthesis processes developed by companies like Shandong Dongyue have reduced unit production costs by 20% and improved product consistency by 30%. In the semiconductor field, domestically produced polysilazane has achieved import substitution in the preparation of 12-inch wafer passivation layers, breaking the long-term monopoly of companies like Merck (Germany) and AZ (Japan). With the rise of strategic emerging industries such as third-generation semiconductors and commercial aerospace, polysilazane is shifting from "following" to "running alongside" and even "leading" in some areas.
