Thermal analysis of the Bi2O3-Er2O3-Zro2 pigments

The synthesis of new compounds based on Bi 2 O 3 is investigated because they can be used as new ecological inorganic pigments. Chemical compounds of the Bi 2−x Er x/2 Zr 3x/8 O 3 type were synthetized. The host lattice of these pigments is Bi 2 O 3 that is doped by Er 3+ and Zr 4+ ions. The incorpo...

Zusammenfassung:	The synthesis of new compounds based on Bi 2 O 3 is investigated because they can be used as new ecological inorganic pigments. Chemical compounds of the Bi 2−x Er x/2 Zr 3x/8 O 3 type were synthetized. The host lattice of these pigments is Bi 2 O 3 that is doped by Er 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.
