Abstract: | New inorganic compounds having the general formula (Bi2O3)1−x
(Lu2O3)
x
(x ranges from 0.1 to 0.5) displaying orange colours have been synthesized by traditional solid-state route, as viable alternatives
to lead, cadmium and chromium based yellow toxic inorganic pigments. The host lattice of these pigments is Bi2O3 that is doped by Lu3+ ions. The goal was to develop conditions for the synthesis of these compounds and to determine the influence of calcination
temperature and lutetium content on their colouring effects. The simultaneous TG-DTA measurements were used for determination
of the temperature region of the pigment formation and thermal stability of pigments. The pigments were also evaluated from
the standpoint of their structure and particle sizes. |
