Abstract: The effect of dopants on the structural states of the YBO$_3$ and ScBO$_3$ borates during sequential isothermal annealings of the amorphous precursor state and the batch from a mixture of micropowders of initial rare-earth metal oxides of the same composition has been investigated using X-ray diffraction. It has been demonstrated that, in both cases, the phase sequences of rare-earth metal borates differ substantially from each other. Possible factors responsible for the strong effect of dopants on the structural sequences during the synthesis of the YBO$_3$ and ScBO$_3$ borates from the amorphous precursor state have been analyzed.
