Abstract: 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.
