Fabrication, mechanical properties, and electrical conductivity of Co{sub 3}O{sub 4} ceramics

Journal Article · · Journal of the American Ceramic Society
Well-densified Co{sub 3}O{sub 4} ceramics (98.3% of theoretical) have been fabricated by the combined use of hot pressing (800 C/1 h/30 MPa) and hot isostatic pressing (880 C/2 h/196 MPa). Their Vickers hardness and fracture toughness are 10.3 GPa and 4.2 MPa{center_dot}m{sup 1/2}, respectively. They exhibit a high electrical conductivity of 3.35 {times} 10{sup 1}S{center_dot}cm{sup {minus}1} at 800 C.
