Abstract

Co-precipitation compound precursors-hydrothermal processing was employed to synthesize Ni/Cu/Al₂O₃/ZrO₂ composite powder, and ZrO₂-based composite ceramics was prepared. The technology recycled the metal of nickel, copper and aluminum from sludge, and the recovery rate of nickel was up to 95.5%. The property of ZrO₂-based composite ceramics was improved because of the existence of nickel and copper particles. The fracture toughness of Ni/Cu/Al₂O₃/ZrO₂ composite ceramics was 8.52 MPa·m^1/2 and the compressive strength was 51 MPa, showing the increase by 2.54 times and 1.5 times, respectively, compared with those of pure ZrO₂ ceramics.
