ABSTRACT:
The process for producing zirconium based pigments (also known as stains) comprises the direct use of plasma disassociated zirconium sand. The sand is comminuted to a suitable particle size, mixed with a color determining agent such as ammonium metavanadate and a mineralizer such as sodium fluoride, after which the resulting mixture is calcined to bring about a reaction between the zirconium sand and the color determining agent to produce the required pigments. The resulting calcined pigment is then ground to a suitable particle size ready for application to ceramic tiles.
