Method and device for preparing scandium-zirconium powder
The invention provides a method and a device for preparing scandium-zirconium powder. The method comprises the following steps: mixing a scandium-containing solution and a zirconium-containing solution to obtain a scandium-zirconium mixed solution; putting the scandium-zirconium mixed solution into a microwave reactor or an ultrasonic reactor, then adding a precipitant into the scandium-zirconiummixed solution under the action of microwave heating or ultrasonic waves, and adjusting the pH value of the system to be 7-11, so that the system is subjected to a precipitation reaction to obtain a scandium-zirconium precursor solution; filtering a scandium-zirconium precursor solution to obtain a precipitate; then sequentially carrying out water washing, alcohol washing and drying on the precipitate to obtain a scandium-zirconium precursor; calcining the scandium-zirconium precursor to obtain scandium-zirconium powder. The scandium-zirconium powder is prepared by utilizing a microwave or ultrasonic-assisted coprecipitation method, so that the problem that a product obtained by a coprecipitation method in the prior art is easy to agglomerate is effectively solved, and the conductivity ofthe scandium-zirconium powder serving as solid electrolyte powder is correspondingly improved.
本发明提供了一种制备钪锆粉体的方法及装置。该方法包括以下步骤：将含钪溶液、含锆溶液进行混合，得到钪锆混合溶液；将钪锆混合溶液置于微波反应器或超声波反应器中，然后在微波加热或超声波的作用下向其中加入沉淀剂并调节体系的pH值为7～11，以使体系进行沉淀反应，得到钪锆前驱体溶液；将钪锆前驱体溶液进行过滤，得到沉淀物；然后依次对沉淀物进行水洗、醇洗、干燥，得到钪锆前驱体；煅烧钪锆前驱体，得到钪锆粉体。本发明利用微波或超声波辅助共沉淀法制备钪锆粉体，有效解决了现有技术中共沉淀法的易团聚问题，相应有助于提高其作为固体电解质粉体的电导率。
