Abstract: The features of the phase formation of pure lanthanum borate during solid-phase synthesis from an amorphous precursor state and from a homogenized mixture of initial oxide micropowders have been investigated using X-ray diffraction methods. It has been shown that LaBO$_3$ phase sequences obtained in both cases significantly differ from each other. The role of cross doping with Y, Sc, and La on the La$_{0.95}$Sc$_{0.05}$BO$_3$, La$_{0.95}$Y$_{0.05}$BO$_3$, Y$_{0.95}$La$_{0.05}$BO$_3$, and Sc$_{0.95}$La$_{0.05}$BO$_3$ phase sequence during synthesis from the amorphous precursor state has been clarified.
