▎ 摘　　要

NOVELTY - Preparing high-temperature-resistant acoustic emission sensing material comprises (i) heating titanium source, zirconium source, acid and lead source in the presence of solvent to obtain powder material, (ii) mixing graphene nitride with the powder material to obtain a mixture A, and forming the mixture A to obtain the molded body; and (iii ) sintering the molded body to obtain the high temperature resistant acoustic emission sensing material. USE - The method for preparing high temperature resistant acoustic emission sensing material is used in a high temperature resistant sensor (claimed). ADVANTAGE - The high temperature resistant acoustic emission sensing material has high tolerance temperature (temperature is more than 600℃), good heat stability and high temperature resistance, and is good for industrialization. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a high temperature resistant acoustic emission sensing material, is prepared as mentiomned above.
