摘要: An unitary layered ceramic structure is disclosed which comprises co-sintered layers. The a sintered central layer of yttria stabilized zirconia ("YSZ") about 8 mole percent and having density at least 95% theoretical, outer layers strontium lanthanum manganite ("LSM") the approximate molecular composition La 0 .8 Sr .2 MnO 3 , from 50 to 60% interconnected porosity 40 50% with an pore diameter one micron five microns. sandwiched by bonded essentially free significant amounts manganese. A process for making composition-of-matter also involves tape casting LSM then on top thereof YSZ tape. presintering powder 1250° F., crushing presintered commercially available powder, forming slurry crushed LSM, binder solvent, allowing air dry. mixture submicron size particle milled dispersant solvent disperse particles thereby dispersed slurry. cast dried If desired, third can be layer. After drying composite LSM/YSZ LSM/YSZ/LSM tapes are fired 1300° C. No migration manganese into was observed scanning electron microscope/edax in multilayer
