The synthesis of binary zinc(II)¯nickel(II) cyclo-tetraphosphates as new special pigments

The synthesis of new inorganic pigments has been investigated, with the goal of preparing heat stable and anticorrosive pigments. The synthesis of the title pigments is based on temperature calcination of the starting materials, and the optimum reaction conditions for this process have been assessed. The pigments have been evaluated from Athe standpoint of their structure, colour hue and ability to dye ceramic glazes. New binary condensed phosphates were synthesised based on results of thermal analyses. These new compounds were developed with environmentally friendly special pigments in mind.
