dc.description.abstract |
The paper deals with the preparation of the inorganic pigments of general formula
RE0.98Ca0.02FeO3, where RE = La, Gd, Lu, Tm, Yb and Ho. The pigments were
prepared by the conventional ceramic method, i.e. solid state reaction. As initial
components were used Ln2O3, CaCO3 and two sources of Fe components, either
Fe2O3 or FeOOH. The reaction mixtures were heated at the temperatures of 800,
900 and 1000 °C. The prepared pigments were applied to an organic binding
system and their colour properties evaluated by measuring reflectance in the
visible region of light. The most interesting colour properties were obtained by the
preparation of the sample Lu0.98Ca0.02FeO3. This pigment was prepared by the
calcination of the reaction mixture containing FeOOH and mineralizer LiF at the
temperature of 900 °C. Generally, the mineralizer LiF affects the colour properties
of all the pigments most significantly. |
