Description
技术领域
本发明涉及新材料技术领域,具体为一种高温电子超导体及其制备方法。
背景技术
超导材料是一种在低温下具有零电阻特性和迈斯纳效应的材料,常温时超导材料与常规材料无太大区别,在低温状态下表现出零电阻特性。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,运作时,高温电子超导体中的电子可以将电流快速且低损耗的传递到发动机上,使得电能转换成动能,推动电梯的运行;伺服电机转动时,预烧粉经过两次烧结强度很大,团聚成的微小颗粒强度相叠加,过强的硬度增加了高温电子超导体的耐磨性,降低电机对高温电子超导体的磨损,并且超强导热性可以将伺服电机摩擦产生的热量快速导出,防止伺服电机温度过高而发生故障。
发明内容
本发明的目的在于提供一种高温电子超导体及其制备方法,以解决现有技术中存在的问题。
为了解决上述技术问题,本发明提供如下技术方案:一种高温电子超导体的制备方法,其特征在于,制备高温电子超导体的工艺流程为:
生料制备、预烧粉制备、乙酸锌制备、物料制备、氧化锌前驱体制备、氧化锌凝胶制备、改性氧化锌凝胶制备、超导基料制备、成品。
进一步的,所述高温电子超导体的制备方法主要包括以下具体步骤:

与现有技术相比,本发明所达到的有益效果是:
本发明将氧化铋、氧化铅、碳酸锶、碳酸钙和氧化铜球磨之后制成生料,将生料在四方相氧化锆瓷舟内放电等离子高温预烧,研细后得到预烧粉;将乙酸锌水解后,经过雾气雾化为气溶胶微液滴,在反应器中与单水氢氧化锂反应,干燥后得到物料,将物料进行热解,得到氧化锌前驱体,使用凝胶溶胶法将氧化锌前驱体制成氧化锌凝胶后,将预烧粉填充至氧化锌凝胶内部,得到预改性氧化锌凝胶,直接对预改性氧化锌凝胶进行高温蒸发处理,得到超导基料,将超导基料在氩气气氛下高温煅烧后进行淬火,制得高温电子超导体;生料在氧化锆瓷舟内高温预烧时,在生料粉末的间隙中通入电流并产生高温等离子的能量,此时四方相氧化锆瓷舟中的四方相区域会形成应力集中的巨大张应力,并在高温高压下发生应力转移,使得生料粉末的内部应力增加从而活化,增加生料粉末的分子活性;雾气雾化制得的气凝胶微液滴更细,制得的氧化锌的晶体强度更高,使得高温电子超导体在服役时能耐得住高温;气凝胶微液滴与单水氢氧化锂反应,使得生成的产物填充在气溶胶内部;热解时气态生成物蒸发,固态物质生成沉积到釜底;预烧粉填充在改性氧化锌凝胶内部,与氧化锌前驱体的掺杂更加充分,并在凝胶内部自团聚成为微小颗粒,预防了氧化锌直接加入预烧粉中之后发生的团聚现象,高温蒸发使得凝胶快速收缩失水,将预烧粉包裹在改性氧化锌凝胶的内部,对预烧粉进行限位的同时,铅原子取代了超导基料中的部分锌原子,使得游离的锌原子嵌入在氧化铜晶格的空隙中,侧面辅助超导相的成相,增加超导体的超导性能;氩气环境一方面保护烧结时预烧粉不与大气接触发生反应,一方面氩气可以在烧结时降低预烧粉的反应活性,阻止高温下预烧粉反应杂质的生成,淬火使得预烧粉中的部分晶体发生相变,获得较为坚硬的马氏体结构,增加高温电子超导体硬度的同时,增加其耐磨性。
将制得的高温电子超导体应用在升降电梯中的伺服电机上,运作时,高温电子超导体中的电子可以将电流快速且低损耗的传递到发动机上,使得电能转换成动能,推动电梯的运行;伺服电机转动时,预烧粉经过两次烧结强度很大,团聚成的微小颗粒强度相叠加,过强的硬度增加了高温电子超导体的耐磨性,降低电机对高温电子超导体的磨损,并且超强导热性可以将伺服电机摩擦产生的热量快速导出,防止伺服电机温度过高而发生故障。
