FULLN CHEMICAL Ceramic glaze pigment Pr-Yellow (Zirconium praseodymium yellow ) pigment is a kind of high temperature calcining synthetic inorganic pigments. It's composed of praseodymium oxide, quartz, zirconium dioxide, mineralizer and other raw material through mixing, firing, micro powder processing. It is a yellow inorganic pigment. In the process of high temperature calcination, zirconium oxide (IV), silica (IV) and praseodymium oxide (Pr6O11) with different number of homogeneous, ionization mutual diffusion, form the zircon crystal structure. Its composition also contains one or more of alkali metal halide or a combination of the alkaline earth metal halide. It's suitable in oxidizing atmosphere firing and suitable for all kinds of glazes especially zirconium glazes. Glazes contain too much calcium composition are not conductive to the color.
