Abstract—Phase relations in the CaOBi₂O₃B₂O₃ system have been investigated by X-ray powder diffraction
and differential thermal analyses, and the isothermal section at 600C has been constructed. The formation of
ternary compounds at the component ratios 1CaO : 1Bi₂O₃ : 1B₂O₃ (CaBi₂B₂O₇) and 1CaO : 1Bi₂O₃ : 2B₂O₃
(CaBi₂B₄O₁₀) has been established X-ray diffraction characteristics of these phases are presented.
