摘 要：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·m1/2 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.
