发明名称 Process to manufacture colored pigments based on zircon
摘要 A process for making colored pigments based on zircon is described whereby a mixture of zirconium halide, silicon halide and a metal halide chromophore are oxidized at a temperature in the range of from about 600 DEG to about 1400 DEG C. This combustion process may be conducted in much less time than prior art procedures which calcine zirconium oxide, silicon oxide and a chromophore. Additionally, the resultant particles are sufficiently small to enable the pigment to be used immediately without need for a subsequent grinding or pulverization step, as typically required by the prior art.
