摘要：

Well-dispersed lithium niobate powders with an ideal stoichiometry were rapidly prepared at 650 A degrees C by a molten salt method, with Li2CO3 and Nb2O5 as raw materials. The dwelling time was 5 min. Li2SO4-Na2SO4 was used as flux in the present work, which can lead to stoichiometric lithium niobate powders due to its very fast chemical reactions during the whole process. IR spectral characteristics strongly support the stoichiometric composition of our present powder samples.
