Abstract cerium nitrate and phosphoric acid as raw material, phosphoric acid precipitation method cerium nanofluid. XRD, TEM, SEM, and other means of the reaction concentration, dropping, dispersing agent, stirring, reaction temperature and other conditions of cerium phosphate nano-fluid performance. The results showed : precipitation can be prepared cerium phosphate nano-fluid, as prepared by the needle of cerium phosphate, diameter of about 40-50nm in length 1μm. reactant concentrations of 0.2M, cerium phosphate nanofluids the best stability; CTAB dispersing agent, the nano-fluid dispersion best; Ultrasonic agitation better results in magnetic stirring; the reaction temperature of 35 ° C to 40 ° C, the stability of nanofluids better; cerium phosphate nano-fluid viscosity of the solid content increases, and the same solid content increases under the CTAB cerium phosphate nano-fluid than the viscosity increases larger.
你看看肯定有好多不对的 你在修改下 我就提供这些了 哈哈
