摘要：
Well-densified Co3O4 ceramics (98.3% of theoretical) have been fabricated by the combined use of hot pressing (800 degrees C/1 h/30 MPa) and hot isostatic pressing (880 degrees C/2 h/196 MPa). Their Vickers hardness and fracture toughness are 10.3 GPa and 4.2 MPa . m(1/2), respectively. They exhibit a high electrical conductivity of 3.35 x 10(1) S . cm(-1) at 800 degrees C.
