On March 22, the State Intellectual Property Office’s information shows that Puyang Punay High-Temperature Materials (Group) Co., Ltd. has applied for a patent titled “A Micro-Expansion Aluminum Silicon Carbide Carbon Brick and Its Preparation Method.” The application publication number is CN121698643A, the application number is CN202610011557.8, the publication date is March 20, 2026, and the application date is January 6, 2026. The inventors are Chen Wangxue, Xu Wei, Liu Ziyu, Xia Changhai, Sun Ronghai, Guo Zhenfeng, Meng Wupeng, Yang Lantian, Zhang Zhuangzhuang, Hu Huaizhen. The patent agency is Beijing Guanyu Intellectual Property Agency (Special Partnership), patent agent Wang Daochuan. The classification codes are C04B35/103 and C04B35/622.

The patent abstract states that the invention discloses a micro-expansion aluminum silicon carbide carbon brick and its preparation method, belonging to the field of aluminum silicon carbide carbon bricks. The micro-expansion aluminum silicon carbide carbon brick is prepared from the following raw materials: 25-35 parts of high-alumina bauxite, 31-49 parts of brown fused alumina, 8-12 parts of aluminum-magnesium spinel, 6-10 parts of flake graphite, 6-12 parts of silicon carbide, 2-4 parts of electric-fused magnesia, 4-5 parts of binder, and 2-3 parts of composite antioxidant. The binder is pre-mixed from modified phenolic resin and rare earth oxides in a mass ratio of 1:0.4-0.6, where the modified phenolic resin is prepared by modifying phenolic resin with molybdenum sulfide. The aluminum silicon carbide carbon brick produced by this method can improve its resistance to erosion, effectively reduce iron seepage and brick falling during use, and provides a new technical approach for long-life, high-reliability applications of aluminum silicon carbide carbon bricks in high-temperature equipment linings.
