M. Trojan et al., UTILIZATION OF DERIVATOGRAPH FOR STUDY OF SYNTHESIS OF NEW INORGANIC PIGMENTS, JOURNAL OF THERMAL ANALYSIS AND CALORIMETRY, 53(2), 1998, pp. 639-647
In our laboratory, the synthesis of new inorganic pigments is followed
by thermal analysis using a Derivatograph apparatus. The first inform
ation about the temperature region of the formation of the pigments in
vestigated is provided by thermal analysis. The main attention is di r
ected to the preparation of high-temperature colour pigments, lightfas
tness colour pigments, anticorrosive pigments, new ecological inorgani
c pigments and luminescent pigments. All inorganic pigments are useful
for colouring of ceramic glazes, enamels, plastics, paints, cements a
nd other building systems. The synthesis of all these pigments is base
d on temperature calcination of starting materials. Tens of new inorga
nic pigments have been prepared thanks to methods of thermal analysis.
These synthesis are described in more than 100 Czech patents.
