A process is described, for producing zirconia-based multi-phasic ceramic composite materials, comprising the steps of: providing at least one ceramic suspension by dispersing at least one ceramic zirconia powder in at least one aqueous medium to obtain at least one matrix for such composite material; providing at least one aqueous solution containing one or more inorganic precursors and adding such aqueous solution to such ceramic suspension to surface modify such ceramic zirconia powder and obtain at least one additived suspension; quickly drying such additived suspension to obtain at least one additived powder; heat treating such additived powder to obtain at least one zirconia powder coated on its surface by second phases; and forming such zirconia powder coated on its surface by second phases. |
