(Ag0.9Li0.1)(Nb1-yTay)O3纳米瓷粉的制备与表征

摘要

A series of (Ag0.9Li0.1)(Nb1-yTay)O3 ceramic powders were prepared by an aque-chemical method. The optimized calcination temperature, time and crystal lattice were studied by TG-DTA, IR, XRD and TEM. The results show that the optimized conditions were calcination of the precursor at 800℃ for 2 h. The ceramic powder thus prepared was rhombohedral with the average grain size of 48 nm.
