All-solid-state reference electrode based on lithium lanthanum titanate ceramic and preparation method thereof
The invention discloses an all-solid-state reference electrode based on lithium lanthanum titanate ceramic (Li0.35La0.55TiO3) and a preparation method of the all-solid-state reference electrode. The preparation method comprises the following steps: mixing LaCl3, LiOH and TiCL4 in proportion, heating, drying, sintering, pressing into a sheet-shaped body, heating the sheet-shaped body at 1300 DEG Cfor 6 hours, polishing, and bonding an Ag or Cu electrode on the sheet-shaped body. Compared with a standard Ag/AgCl reference electrode, the all-solid-state reference electrode is more stable and easy to store. After high-temperature and high-pressure (400 DEG C and 35 Mpa) treatment is carried out for 3 hours, the potential of the LLTO all-solid-state reference electrode can be kept stable, which indicates that the electrode resists high temperature and high pressure, so that the test range is wider.
本发明公开了一种基于钛酸镧锂陶瓷（Li0.35La0.55TiO3）的全固态参比电极及制备方法，其制备是将LaCl3、LiOH和TiCL4按比例混合加热、烘干并烧结后压成片状体，将片状体在1300℃下加热6h后打磨平整，在平整片状体上粘结Ag或者Cu电极。与标准Ag/AgCl参比电极相比，本发明的全固态参比电极更稳定，易保存。经过高温高压（400℃、35Mpa）处理3h后，LLTO全固态参比电极的电势还能保持稳定，说明该电极耐高温高压，因此测试范围更广泛。
