Abstract

The invention provides a preparation method of a trace element composite doping modified tin antimony oxide (ATO) ceramic target. The preparation method is characterized by firstly weighing ATO powder with antimony oxide mass percentage of 0.1-1.0% and then respectively weighing manganese oxide and copper oxide powder to serve as composite doping modifying agents according to 0.5-1.0% of the total mass of the ATO powder; ball-milling the powder together with an organic solvent and mixing balls in a mass ratio of (1:1:1)-(1:2:1), putting the obtained slurry into a baking oven to be baked at low temperature until organic solvent evaporation is completed, then grinding the product and sieving the product with an open sieve to obtain mixed powder; after the mixed powder is subjected to intercooling and isostatic pressing in a die, sintering the green body in the air atmosphere by adopting the mode of pressureless sintering, thus obtaining the ceramic target, wherein the heating rate is 0.5-5 DEG C / min, the sintering temperature is 1200-1450 DEG C and the insulating time is 1-10 hours. The obtained modified ATO ceramic target has the advantages of relatively small composite doping amount, high compactness, relatively high normal temperature electrical conductivity and the like.

Description

technical field [0001] The present invention relates to a method for preparing antimony tin oxide (ATO) ceramic target compound doped with trace elements, which can prepare high-density, high-conductivity antimony tin oxide ceramics, which can be used as a target for preparing transparent conductive films by physical vapor deposition. material. Background technique [0002] With the vigorous development of my country's economy and technology, the photovoltaic industry and optoelectronic information industry occupy a pivotal position in contemporary society as the medium of information transmission. With their rapid development, the development of transparent conductive films with high conductivity and high visible light transmittance The demand is also increasing day by day. Due to the high transmittance in the visible light region, low resistivity (as low as 10-4Ω·cm), and unique properties such as high reflectivity in the infrared region and strong attenuation to microwave...
