Embodiment 1
[0058] LiNbO synthesized by sol-gel method 3 Precursors were added and dissolved with a 10-fold molar ratio of FeCl 3 , 2 times the molar ratio of HCl aqueous solution, stirring at 90 ° C for two days. Filter out particle 1, add the above dissolved FeCl with a molar ratio of 10 times 3 (1.6mol / L), 2 times the molar ratio of HCl in aqueous solution, and the mixed system is placed in a high-temperature and high-pressure reaction vessel, and reacted at 130°C for three days. Filter particle 2, and finally add the above dissolved FeCl with a molar ratio of 10 times 3 , 2 times the molar ratio of HCl in water, and the mixed system is placed in a high-temperature and high-pressure reaction vessel, and reacted at 160 ° C for three days to obtain the intermediate product. During the reaction, all the lithium ions and part of the niobium ions in the raw materials are dissolved by the hydrochloric acid solution, the hydrogen ions in the hydrochloric acid solution are exchanged into th...
