The preparation method comprises the following steps: mixing and stirring the following components in parts by weight: 10-30 parts of a zirconium-containing compound, 1-5 parts of an aluminum-containing compound, 6-17 parts of a lanthanum-containing compound, 1-20 parts of a polymerization inhibitor, 10-150 parts of urea and 400-600 parts of water to obtain a first mixture; heating the first mixture, carrying out heat preservation for a preset time, filtering, washing and drying to obtain a precursor; mixing the precursor with a lithium salt, and grinding to obtain mixed powder; sintering the mixed powder to obtain a finished product. The method is simple in process, low in production cost and suitable for large-scale mass production, and the cubic-phase lithium lanthanum zirconium oxide which is uniform in crystalline phase, has the particle size at the quasi-micron level and is good in ionic conductivity can be obtained under the condition of low-temperature sintering.
本发明公开了一种立方相锂镧锆氧及其制备方法，包括：按重量份计，将含锆化合物10～30份、含铝化合物1～5份、含镧化合物6～17份、阻聚剂1～20份、尿素10～150份和水400～600份混合搅拌，得到第一混合物；将所述第一混合物加热并保温预设时间后，过滤、洗涤、干燥后得到前驱体；将所述前驱体和锂盐混合，再经研磨处理后得到混合粉末；所述混合粉末烧结后得到成品。本发明工艺简单、生产成本低，适应于大规模量产，能够在低温烧结的条件下，得到晶相均一、粒子大小在准微米级且离子电导率良好的立方相锂镧锆氧。
