Abstract: <P>PROBLEM TO BE SOLVED: To provide a solid electrolyte nanoporous material high in ion conductivity.  <P>SOLUTION: YSZ is mixed with 10 wt.% of polymethyl methacrylate particles in an average particle size of 150 nm by using water as a solvent in a planetary pot mill for three minutes. After dried, the mixture is formed into a green compact by uniaxial press molding and CIP. The green compact is calcined under a nitrogen atmosphere at 1,400°C, to form a sintered compact of YSZ having nano closed pores. When a porosity of the sintered compact is measured by Archimedes' method, the porosity is 10 wt.%. In succession, the closed pores of 100-200 nm in pore diameter are observed in the microstructure observation of a cross-section of the sintered compact. An ionic conductivity of the sintered compact is increased by a factor of about 1.5 comparing to a sintered compact of YSZ not having closed pores.  <P>COPYRIGHT: (C)2010,JPO&INPIT
