We studied the sintering of mixed powders in which either alumina or aluminum was coated with polysiloxane derived from aqueous slurry in order to avoid using organic solvent and to confirm the change of sintering process by coating only one of the powders. We found that similar characteristics of porous alumina can be obtained by sintering the mixed powder derived from an aqueous slurry and the mixed powder derived from an ethanol slurry. Coating the alumina powder with polysiloxane prevented the volume expansion of samples during sintering, thus increasing the density of the porous alumina and wettability between alumina and aluminum.
