High-temperature electronic superconductor
The invention discloses a high-temperature electronic superconductor and a preparation method thereof. The preparation method comprises the following steps: ball-milling bismuth oxide, lead oxide, strontium carbonate, calcium carbonate and copper oxide to prepare a raw material, pre-sintering the raw material in a tetragonal phase zirconium oxide porcelain boat at high temperature by discharge plasma, and grinding to obtain pre-sintered powder; the preparation method comprises the following steps: hydrolyzing and atomizing zinc acetate into aerosol micro-droplets, reacting the aerosol micro-droplets with lithium hydroxide monohydrate to obtain a material, drying the material, pyrolyzing to obtain a zinc oxide precursor, preparing the zinc oxide precursor into zinc oxide gel by using a gel-sol method, filling the pre-sintered powder into the zinc oxide gel to obtain pre-modified zinc oxide gel, and drying the pre-modified zinc oxide gel to obtain the lithium ion battery cathode material. And carrying out high-temperature evaporation treatment on the pre-modified zinc oxide gel to obtain a superconductive base material, carrying out high-temperature calcination on the superconductive base material, and then carrying out quenching to obtain the high-temperature electronic superconductor. The high-temperature electronic superconductor prepared by the invention is applied to a servo motor in an elevator, and is superconductive and wear-resistant, and meanwhile, the ultrahigh thermal conductivity can prevent the servo motor from malfunctioning due to overhigh temperature.
本发明公开了一种高温电子超导体及其制备方法。本发明先将氧化铋、氧化铅、碳酸锶、碳酸钙和氧化铜球磨后制成生料，将生料在四方相氧化锆瓷舟内放电等离子高温预烧，研细后得预烧粉；将乙酸锌水解，雾化为气溶胶微液滴后，与单水氢氧化锂反应，得物料，将物料干燥后进行热解，得氧化锌前驱体，使用凝胶溶胶法将氧化锌前驱体制成氧化锌凝胶，将预烧粉填充至氧化锌凝胶内，得预改性氧化锌凝胶，对预改性氧化锌凝胶进行高温蒸发处理，得超导基料，将超导基料高温煅烧后进行淬火，制得高温电子超导体。本发明制备的高温电子超导体应用在升降电梯中的伺服电机上，在超导电、耐磨的同时，超高导热性可以防止伺服电机温度过高而发生故障。
