چکیده انگلیسی
Alumina platelets and a pulsed electric current sintering (PECS) technique were used to form porous alumina with highly oriented grains in one direction. A slurry consisting of alumina platelets, distilled water, and organic binders was spread over a gypsum board to form a green sheet. Pellets 14 mm in diameter were punched from the sheet and preheated at 800 °C to burn off the binders. The preheated pellets were placed in a carbon die, which was then positioned within the PECS device. After heating at 1400 °C and 30 MPa for 5 min, porous alumina with 80.8% density was obtained. Parallel to the pressing direction, the thermal conductivity and bending strength of the porous body were 22.4 W mâ1 Kâ1 and 404 MPa, respectively. Perpendicular to the pressing direction, on the other hand, the thermal conductivity and bending strength of the porous body were 10.8 W mâ1 Kâ1 and 217 MPa, respectively.
