PROCESS FOR THE PRODUCTION OF A ZIRCONIA-BASED, COLOURED, IN PARTICULAR GREY, ARTICLE AND A ZIRCONIA-BASED COLOURED DECORATIVE ARTICLE OBTAINED USING THIS PROCESS
A process for the production of a grey zirconia-based article wherein a first mixture includes a zirconia powder forming the base constituent, 4% to 15% by weight of at least one stabiliser selected from among the group of oxides including yttrium oxide, magnesium oxide and calcium oxide alone or in combination, 0.1% to 1% by weight of a vanadium oxide powder (V2O5), 0.1% to 1% by weight of a chromium oxide powder (Cr2O3) and 0.1% to 1% by weight of a silicon oxide powder (SiO2); making a second mixture including the first mixture and a binder; making a granulated mixture by conducting a granulation of the second mixture; forming a blank by giving this second granulated mixture the shape of the desired article; sintering the blank in air for at least thirty minutes at a temperature in the range of between 1250° and 1550° C.
