Preparation method of LLZTO ceramic tube with large length-diameter ratio
The invention relates to a preparation method of an LLZTO ceramic tube with a large length-diameter ratio, which comprises the following steps: (S1) feeding a lithium source, a lanthanum source, a zirconium source and a tantalum source, and pre-sintering to obtain LLZTO pre-sintered powder; (S2) adding water into the LLZTO pre-sintered powder to prepare slurry, and carrying out wet sanding to enable the particle size of the material to be in a submicron level; (S3) carrying out spray granulation on the sanded slurry, so as to obtain LLZTO granulation powder; (S4) uniformly mixing the granulation powder, a plasticizer, a binder and water, sealing and aging to obtain an aged material; (S5) loading the aged material into a rod-shaped mold, compacting, and carrying out cold isostatic pressing to obtain a green body; and (S6) adding LLZTO mother powder at the bottom of the sintering container as buried powder, placing the green body on the buried powder, sintering and cooling to obtain the LLZTO ceramic tube with the large length-diameter ratio. By adjusting process parameters and matching the plasticizer and the adhesive, the obtained ceramic tube with the large length-diameter ratio has excellent flexibility and strength, the geometrical shape meets the integration requirement, and the ceramic tube can be conveniently compounded with a collective material.
本发明涉及一种大长径比LLZTO陶瓷管的制备方法，包括以下步骤：(S1)将锂源、镧源、锆源、钽源投料，进行预烧，得到LLZTO预烧粉料；(S2)LLZTO预烧粉料加水配制为的浆料，进行湿法砂磨，使物料粒径为亚微米级别；(S3)将砂磨后的浆料进行喷雾造粒，得到LLZTO造粒粉；(S4)造粒粉、增塑剂、粘结剂和水混合均匀，密封陈腐，得到陈腐料；(S5)将陈腐料装入棒状模具，振实，冷等静压压制得到生坯；(S6)在烧结容器底部加入LLZTO母粉作为埋粉，生坯置于埋粉上，进行烧结，冷却，得到大长径比LLZTO陶瓷管。本发明通过调工艺参数，以及增塑剂和粘接剂的配合，所得大长径比陶瓷管具有优异的柔韧性和强度，几何形状满足集成要求，便于与集体材料复合。
