Preparation method of nanometer aluminum oxide/ gadolinium-aluminum perovskite composite powder
The invention relates to a preparation method of nanometer aluminum oxide/ gadolinium-aluminum perovskite composite powder, and aims at solving the technical problems that an existing preparation method of Al2O3/GdAlO3 composite powder is high in synthetic temperature, not suitable for large scale synthesis and high in cost, and difficultly controls a quick reaction. The preparation method of the nanometer aluminum oxide/ gadolinium-aluminum perovskite composite powder includes: 1, preparing a gadolinium nitrate solution; 2, preparing an aluminum nitrate solution; 3, precipitating the gadolinium nitrate solution and the aluminum nitrate solution together; 4, centrifuging and drying the gadolinium nitrate solution and the aluminum nitrate solution after the gadolinium nitrate solution and the aluminum nitrate solution are precipitated together; 5, performing roasting. The preparation method of the nanometer aluminum oxide/ gadolinium-aluminum perovskite composite powder has the advantages of using an alcohol-water heating method according to the principle that an electric medium constant of an alcohol-water solution is obviously reduced and ultrafine particles which are evenly dispersed are easy to form, is performed under mild conditions easy to control, can adapt to different aluminum oxide/ gadolinium-aluminum perovskite composite powder systems, and simultaneously can control two phases of compositions, is low in production cost and simple, can not cause pollution on environment, can prepare the nanometer composite powder good in dispersion performance, and can achieve large scale volume production.
