材料汇·2025-12-31 11:27Core Viewpoint - The article discusses the strategic transformation of China's new materials industry by 2025, emphasizing a "three-dimensional war" approach that includes "fortress materials" for national security, "sovereign materials" for technological independence, and "fusion materials" for future industry definition [3]. Group 1: Fortress Materials - The development of safety dimension materials is closely tied to national core interests, focusing on absolute reliability and performance under extreme conditions rather than cost-effectiveness [5]. - A significant breakthrough in 2025 is the mass production of the fourth-generation single crystal high-temperature alloy turbine blades, which can withstand temperatures above 1200°C and have a lifespan increased by nearly 50% compared to previous generations [8][10]. - Continuous silicon carbide fibers have transitioned from laboratory preparation to stable engineering mass production, with a production capacity of hundreds of tons, marking a strategic leap in the aerospace sector [14][15]. Group 2: Sovereign Materials - Sovereign materials focus on achieving "self-control" and enhancing industrial competitiveness, particularly in strategic sectors like semiconductors and high-end manufacturing [40]. - In the semiconductor sector, the production of 12-inch silicon wafers has reached a milestone with over 500,000 monthly shipments, and significant advancements in low-oxygen high-resistivity silicon wafer technology have been made [44]. - The domestic supply ratio of 300mm semiconductor silicon wafers is expected to increase from 15% to 40% by the end of 2025, significantly reducing reliance on imports [45]. Group 3: Fusion Materials - The fusion materials dimension represents a shift towards creating new demands and defining new products, characterized by the integration of materials science with cutting-edge fields like artificial intelligence and synthetic biology [72]. - AI-driven platforms for materials research have emerged, enabling rapid property prediction and screening, significantly reducing development cycles for critical materials [74]. - The integration of intelligent materials in robotics is evolving, allowing materials to interact with their environment and make autonomous decisions, marking a shift from passive components to intelligent structures [77].
