Abstract
Porous alumina ceramics with unidirectionally aligned continuous pores were
fabricated via the slurry coating of fugitive fiber. Cotton thread was coa
ted with ceramic slurry by pulling it through the slurry, and specimens wer
e produced by spooling the coated thread. The obtained porous alumina ceram
ics had an average pore diameter of 165 mum, 35% open porosity, and a bendi
ng strength of 160 MPa, It was suggested that the pore size and the porosit
y could be adjusted using the diameter of the cotton thread and the solids
concentration of the slurry respectively.
