Precursor for preparing ceramic material, ceramic material and preparation method
The invention discloses a precursor for preparing a ceramic material, the ceramic material and a preparation method, and belongs to the technical field of ceramic materials. The method specifically comprises the following steps: adding a lithium source, an aluminum source, a germanium source, a titanium source, a phosphorus source and a sintering additive into a solvent in proportion to form a mixture; performing spray drying on the mixture to obtain a precursor; putting the precursor into heating equipment for heat treatment, and carrying out heat treatment for 1-10 hours at the temperature of 500-700 DEG C to obtain pre-sintered powder; carrying out crushing treatment on the pre-sintered powder, and uniformly mixing after the treatment is completed; and carrying out heat treatment on the uniformly mixed pre-sintered powder again at 800-1500 DEG C for 120 hours to obtain the solid electrolyte powder material. The sintering additive is added into the mixture, no obvious foaming phenomenon exists in the solid-phase reaction, the wall sticking phenomenon of the sample after sintering is effectively avoided, subsequent crushing treatment is facilitated, and the production efficiency is improved.
本发明公开了用于制备陶瓷材料的前驱体、陶瓷材料及制备方法，属于陶瓷材料的技术领域。该方法具体包括以下步骤：将锂源、铝源、锗源、钛源、磷源与烧结添加剂按比例加入溶剂中形成混合体；喷雾干燥上述混合体获得前驱体；将上述前驱体放入加热设备中进行热处理，在500~700℃下热处理1~10h，得到预烧粉体；将预烧粉体进行破碎处理，处理完成后混合均匀；将混合均匀后的预烧粉体再次热处理，800~1500℃下热处理1~20h，得到固体电解质粉体材料。本发明在混合物中加入烧结添加剂，在固相反应中没有明显的发泡现象，有效避免样品在烧结后的粘壁现象，便于后续的破碎处理，提高生产效率。
