    • Disclosed herein is a method and apparatus for fabrication of a thin film superconductor. Specifically, provided is a method and apparatus for fabrication of a thin film superconductor using spray pyrolysis chemical vapor deposition, comprising dissolving an inorganometallic compound as a raw material in distilled water to prepare a precursor solution, spraying the resulting precursor solution in a state of fine droplets, and coating an epitaxial thin film on a substrate (such as a ceramic material, a nickel metal, a nickel alloy, stainless steel or the like) via a pyrolysis process. The method comprises dissolving an inorganometallic compound having a water-solubility in distilled water to prepare a precursor solution; processing the precursor solution into droplets having a size of several μm to several tens of μm and storing the droplets in a raw material storage; transferring the droplets in the storage to a main pipe via a pump and simultaneously supplying the droplets, in conjunction with carrier and reactant gases supplied by operation of a valve, to a nozzle; heating the droplets sprayed from the nozzle by an auxiliary heat source to evaporate the distilled water, thereby preparing fine-sized particles of the inorganometallic compound; elevating a temperature of a heater formed in a table, such that the resulting particles react with the reactant gas to form an oxide; uniformly forming a film of the oxide at opposite sides on a single crystal substrate having a certain texture provided to the table via conveyers, by a ∧ shaped stainless steel plate, thereby forming an oxide template having a certain texture on the upper part of the substrate, and sufficiently heating the single crystal substrate prepared by forming an oxide buffer layer on the resulting oxide template to form an oxide thin film; and subjecting the resulting oxide thin film to an oxygen heat-treatment to complete a thin film superconductor having superconducting properties. That is, the present invention provides a method for fabrication of a thin film superconductor made of REBa2Cu3O7-x (RE = a rare-earth element selected from the group consisting of Y, La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and any combination thereof), using a precursor solution prepared by dissolving an inexpensive inorganometallic compound in distilled water. Therefore, the present invention enables production of superconductors at a significantly lower cost, as compared to the use of a conventional expensive β-chelate compound, i.e., 2,2,6,6-tetramethyl-3,5-heptanedione (tmhd).
    • 本文公开了一种用于制造薄膜超导体的方法和装置。 具体地,提供了使用喷雾热解化学气相沉积制造薄膜超导体的方法和装置,其包括将作为原料的无机金属化合物溶解在蒸馏水中以制备前体溶液,将所得前体溶液以精细状态 并通过热解法在基底(例如陶瓷材料,镍金属,镍合金,不锈钢等)上涂覆外延薄膜。 该方法包括将具有水溶性的无机金属化合物溶解在蒸馏水中以制备前体溶液; 将前体溶液处理成具有几μm至几十μm的液滴并将液滴储存在原料储存器中; 通过泵将存储器中的液滴转移到主管道,同时将液滴与通过操作阀供应的载体和反应物气体一起供应到喷嘴; 通过辅助热源加热从喷嘴喷射的液滴以蒸发蒸馏水,从而制备无机金属化合物的细小颗粒; 升高形成在台上的加热器的温度,使得所得到的颗粒与反应气体反应形成氧化物; 在具有通过输送机提供给桌子的具有特定纹理的单晶基板上的相对侧的氧化物膜均匀地形成, 从而在基板的上部形成具有一定质地的氧化物模板,并且通过在所得到的氧化物模板上形成氧化物缓冲层而制备的单晶基板充分加热以形成氧化物薄膜; 并对所得氧化物薄膜进行氧热处理,以完成具有超导特性的薄膜超导体。 也就是说,本发明提供一种制造由REBa2Cu3O7-x制成的薄膜超导体的方法(RE =选自Y,La,Nd,Sm,Eu,Gd,Tb,Dy的稀土元素 ,Ho,Er,Tm,Yb,Lu及其任意组合),使用通过将廉价无机金属化合物溶解在蒸馏水中制备的前体溶液。 因此,与使用常规的昂贵的β-螯合化合物即2,2,6,6-四甲基-3,5-庚二酮(tmhd)相比,本发明能够以显着更低的成本生产超导体。
