eng	Complex 3d-Metal Phosphates as Ceramic Pigments: Thermal Stability and Colour Properties	An important family of high performance ceramic pigments consists of synthetic crystalline phosphate compounds of two or more different metals. Wide range of colours of the phosphate pigments is typically provided by the content of 3d transition metals (Cr, Mn, Fe, Co, Ni, Cu). The primary demands to this class of pigments include outstanding colour and heat stability as well as resistance to dissolution, chemical agents, and solvent attack. In the field of research in this area two main directions have been developed: on the one hand an economization and improvement of existing pigments, and on the other hand, the discovery and implementation of new compounds with higher performing characteristics. However, due to limitations in available chemistry, very few really new ceramic pigments have been developed in the last decades. Our research group at the University of Pardubice has been engaged for many years in development of new thermally stable ceramic pigments on basis of complex oxide compounds including phosphates. Our last findings in this field include new ceramics which were obtained in ZrP2O7-MII2P2O7 systems (MII = Co, Cu) and also NASICON related phosphates of ZrIV and CrIII or CoII in combination with alkali or alkali-earth metals and lanthanides.
