The synthesis of new compounds based on Bi 2 O 3 is investigated because they can be used as new colour inorganic pigments. Chemical compounds of the Bi 2-x Y x/2 Zr 3x / 8 O 3 type were synthetised. The host lattice of these pigments is Bi 2 O 3 that is doped by Y 3+ and Zr 4+ ions. The incorporation of doped ions provides interesting colours and contributes to a growth of the thermal stability of these compounds. The simultaneous TG-DTA measurements were used for determination of the temperature region of the pigment formation and thermal stability of pigments. This paper also contains the results of the pigment characterization by X-ray powder diffraction and their colour properties.
