I. Technological Breakthrough: From "Bottlenecks" to Independent Control
As a ceramic precursor material, the core technology of polysilazane has long been monopolized by companies such as Merck of Germany and Clariant of Switzerland. In recent years, China has achieved key breakthroughs through collaborative innovation between industry, academia, and research:
Innovative Preparation Process: The sol-gel method developed by the Institute of Chemistry of the Chinese Academy of Sciences has increased product purity to 99.99%, meeting the needs of semiconductor packaging; Hangzhou Qingci New Materials has built China's first continuous production line, reducing production costs by 30% and increasing capacity utilization from 78% in 2025 to 85% in 2030.
Breakthrough in Modification Technology: Addressing the challenge of material reactivity, a team from Xi'an Jiaotong University introduced transition metal elements to develop a Si-B-C-N ceramic precursor with a temperature resistance of 1300°C. This precursor is used in aircraft engine turbine blade protection, enabling components to operate stably at 1200°C. Breaking Patent Barriers: Domestic companies have cumulatively applied for over 500 polysilazane-related patents. The Chinese Academy of Sciences' PSN series products have replaced imported materials and are used in Yangtze Memory Technologies' 3D NAND chip manufacturing.

II. Application Expansion: From Cutting-Edge Fields to Consumer Scenarios
Polysilazane, with its high-temperature resistance, insulation, and corrosion resistance, has achieved large-scale application in multiple fields:
Semiconductor Packaging: As an insulating layer material for chips with a process size below 5nm, this market is expected to exceed 1.5 billion yuan in 2029, accounting for 27% of the overall market. Samsung's Galaxy S21 series motherboards utilize polysilazane encapsulation technology, achieving an IP68+ waterproof rating.
New Energy Revolution: Tesla's Model Y battery module utilizes a polysilazane insulating membrane, increasing energy density by 15%. During road tests of the Toyota Mirai's hydrogen fuel cell's modified proton exchange membrane, operating temperatures increased from 80°C to 180°C, improving efficiency by 15%.
Biomedical Innovation: The University of Tokyo's intelligent, invasive polysilazane oxygen permeability accelerates burn healing by 40% and reduces scar formation by 65%. Environmental Breakthrough: MIT's polysilazane-based desalination membrane achieves a 99.7% desalination efficiency and consumes only one-third the energy of traditional technologies.

III. Industrial Landscape: From Import Dependence to Global Competition
China's polysilazane industry is demonstrating a "Yangtze River Delta Clustering, Pearl River Delta Innovation" landscape:
Capacity Expansion: The industry will add 18,000 tons of new capacity between 2025 and 2030, with electronic-grade products accounting for 60%. The global market share is expected to increase to 49.2% by 2030.
Competitive Competition: Leading companies such as XX New Materials and YY Technology hold a combined 55% market share, while small and medium-sized enterprises are entering niche markets such as aerospace specialty materials and biomedical applications through differentiated competition.
Policy Driven: The 14th Five-Year Plan lists polysilazane as a key material. After 2025, special subsidies will help increase R&D investment to 8.5%, reducing import dependence from 32% to 18%.

Polysilazane is currently moving from the laboratory to large-scale applications, its development path exemplifying the typical pattern of the new materials industry: technological breakthroughs, application expansion, and industrial upgrading. With breakthroughs in cutting-edge technologies such as quantum electronics and self-healing coatings, this material is expected to become a market worth hundreds of billions of yuan by 2030, becoming a "hidden champion" supporting high-end manufacturing.
