The invention belongs to the technical field of electronic ceramic preparation and application, and in particular relates to a method for finely synthesizing ilmenite-structured ZnTiO3 series microwave dielectric ceramic nano powder by using a water-soluble sol-gel process. The method comprises the following steps: 1) preparing a citric acid solution of Zn ions; 2) preparing a citric acid solution of Ti; 3) synthesizing a ZnTiO3 microwave dielectric ceramic nano precursor. As oxides and inorganic nitrate which are low in price are taken as raw materials, and expensive alkoxides are not used, the synthesized powder has the remarkable advantages that the synthesis temperature is low, the ceramic particles are uniform, good dispersity is achieved, the phase is pure, various elements can be finely doped and modified, the prepared powder has the nano particle size (about 30nm), is high in specific surface property and is relatively high in activity, later low-temperature sintering can be achieved, and LTCC application requirements can be possibly met.
