采用热压（800 C/1 h/30 MPa）和热等静压（880 C/2 h/196 MPa）相结合的方法制备了致密的Co {sub 3} O {sub 4}陶瓷（理论值的98.3%）。其维氏硬度和断裂韧性分别为10.3 GPa和4.2 MPa {center_dot} m {sup 1/2}。它们在800 ℃下表现出3.35 {times} 10 {sup 1} S {center_dot} cm {sup {minus} 1}的高电导率。
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.
