Using X-ray diffraction analysis and scanning electron microscopy it was revealed that in an atmosphere of flowing oxygen in the temperature range 700-800C, three new compounds are formed in the Bi sub(2)O sub(3)-TiO sub(2)-TeO sub(2) pseudoternary system. These compounds are Bi sub(2)Ti sub(3)TeO sub(12), Bi sub(2)TiTeO sub(8), and Bi sub(6)Ti sub(5)TeO sub(22), and all the compounds include Te super(6+). All three crystal structures were solved and refined using X-ray powder diffraction data. Based on the results of the phase formation, a solid-state compatibility diagram is proposed.
