摘　　要：纳米流体是一种新型高效换热工质,采用一步湿化学法制备了三种浓度的Ce PO4纳米流体,并对其粒径、Zeta电位和导热系数进行分析。研究表明,制备的0.1mol/L、0.2 mol/L和0.3 mol/L纳米流体平均粒径分别为49.8nm、67.3nm、94.1nm,并具有良好的稳定性,且导热系数随着温度的升高而增加。Nanofluid is a new type of high efficiency heat exchanging medium. CePO4 nanofluid with three concentration was prepared by one-step wet chemical method. And particle size, zeta potential and thermal conductivity were analyzed. The results showed that, the average diameters of prepared 0. lmol/L, 0.2mol/L and 0.3mol/L nanofluids are 49.8nm, 67.3nm and 94.1nm, respectively. All prepared nanofluids have good stability. And the thermal conductivity increases as the temperature increase.
