Patent number: 12017960Abstract: A preparation method of heat-resistant adhesive of silicon-boron-carbon-zirconium modified aluminum-zirconium phosphate for zirconium oxide ceramics is provided. The high-temperature adhesive can generate various high-temperature resistant phases such as zirconia, aluminum phosphate, zirconium phosphate and aluminum borate in situ of the high-temperature adhesive at high temperatures. As the processing temperature increases, the content of zirconia in the high-temperature adhesive continuously increases, and the composition tends to form a stable composite phase mainly composed of aluminum phosphate and zirconia, which makes the composition of the high-temperature adhesive closer to that of zirconia ceramics.Type: GrantFiled: February 2, 2024Date of Patent: June 25, 2024Assignee: Civil Aviation University of ChinaInventors: Qingsong Zhang, Mingchao Wang, Haijun Zhang
