OPTIMIZATION OF SLIP-CAST LA0.8SR0.2CRO3 PEROVSKITE MATERIAL FOR USE AS AN INTERCONNECT IN SOFC APPLICATIONS

La0.8Sr0.2CrO3, for use as an interconnect material for solid oxide fu el cell(SOFC) applications, can be fabricated via a number of differen t routes, including slip casting. This work examines the effect of the various slip compositions on the integrity of the green ceramic. with only the successful slips being sintered, The most successful slip co mposition was 2 wt% KDI(TM) dispersant, 8 wt% poly vinyl-butyral binde r, and 8 wt% plasticiser (50:50 volume mixture of di-n-butyl phthalate : polyethylene glycol), in a 31% toluene:69% 2-propanol solvent system , producing a sintered body with over 96% theoretical density, when si ntered at 1600 degrees C.
