Abstract

See full text

The present disclosure is to provide a method of producing a LTP or LATP crystal particle that has reduced impurity contamination, high crystallinity, and excellent dispersibility. The method of producing a LTP or LATP crystal particle according to the present disclosure includes: preparing glass containing, in molar ratio, 1+x of Li2O, where 0≤x≤1, x of Al2O3, 4−2x of TiO2, 3+y of P2O5, where 1≤y≤4, and from more than y to less than 3y of ZnO; subjecting, after the preparation of glass, the glass to thermal treatment for crystallization; and selectively eluting a substance other than a LTP or LATP crystal through acid treatment.
