The present invention describes a ceramic process for the preparation of zirconia white powders with 3% and 8% of Yttria, in which neither additives are required nor the machined of the white powders after the sintering process. The white powders are manufactured by a ceramic process, which includes commercial powders of stabilised zirconia at 3% and 8% of Y2O3, which are added by a milling process in spex mills and nylamid mills due to their resistance to impact and abrasion with zirconia pellets of 10 and 5 millimetres with a weight ratio of 1:1, this process lasting 5 minutes, then the powder being recovered and homogenized in agate mortars, immediately passing to the press process in an uniaxial press, so as to be subsequently sintered with the different methods that have been previously described.
