Samples with a composition close to LiTaO 3 were prepared by solid state reactions from Li 2 CO 3 and Ta 2 O 5 powders and by a sol-gel method using alkoxides of lithium and tantalum. The successive steps of the LiTaO 3 preparation process were follo

Powders with compositions close to LiTaO3 have been prepared by a sol-gel method using alcoholates of Iithium and tantalum. The granulometry of these powders obtained allowed us to elaborate ceramics at temperatures lower than 1150°C. Comparative di

LiTaO3 powders have been prepared by appropriate hydrolysis of lithium and tantalum alkoxides. Ceramics with high shrinking coefficients have been obtained by sintering of the particles at 1150°C.

LiNbO3 powders have been prepared by appropriate hydrolysis of lithium and niobium alkoxides using a sol-gel process. Ceramics with pretty high shrinkage coefficients and compactness have been obtained by sintering of the particles at 1075 °C.
