Abstract
A process for producing an inorganic doped-zircon pigment includes calcining a base mixture comprising raw plasma-dissociated zircon, a chromophore, and at least one mineralizer, to produce a raw pigment. The raw pigment is refined to obtain an inorganic doped-zircon pigment.
Claims8
A process for producing an inorganic doped-zircon pigment comprising:
- obtaining a raw plasma-dissociated zircon;
- calcining a base mixture of said raw plasma-dissociated zircon, a chromophore and at least one mineralizer to produce a raw pigment;
- and
- refining the raw pigment to obtain an inorganic doped-zircon pigment;
- wherein said raw plasma-dissociated zircon is not subject to milling between the plasma dissociation of the zircon and mixing thereof with the chromophore and the at least one mineralizer.
