Nanometer ceramic target material and preparation method thereof

The invention relates to the technical field of ceramic materials, in particular to a nanometer ceramic target material and a preparation method thereof. The nanometer ceramic target material is applied to heat isolation functional glass, and can solve the problem of easiness in aging in the existing heat isolation functional glass. The nanometer ceramic target material has the advantages that by controlling the technology parameters in the preparation process, the problem of precipitation of metal element due to reduction of the nanometer ceramic target material in the preparation process is effectively solved, and the low density due to forming of air pores in the nanometer ceramic target material is avoided; when the nanometer ceramic target material prepared by the method is applied to the heat isolation functional glass, the physical properties of visible light transmittance and the like of the heat isolation functional glass are further improved, and the heat isolation functional glass has selective abs
