Utilization of Derivatograph for Study of Synthesis of New Inorganic Pigments

In our laboratory, the synthesis of new inorganic pigments is followed by thermal analysis using a Derivatograph apparatus. The first information about the temperature region of the formation of the pigments investigated is provided by thermal analysis. The main attention is directed to the preparation of high-temperature colour pigments, lightfastness colour pigments, anticorrosive pigments, new ecological inorganic pigments and luminescent pigments. All inorganic pigments are useful for colouring of ceramic glazes, enamels, plastics, paints, cements and other building systems. The synthesis of all these pigments is based on temperature calcination of starting materials. Tens of new inorganic pigments have been prepared thanks to methods of thermal analysis. These synthesis are described in more than 100 Czech patents. This revised version was published online in July 2006 with corrections to the Cover Date.
