Tape method of forming a thin layer of doped lanthanum chromite particles and of bonding such on an electrode
This patent describes a method of forming a combustible polymer film containing a thin layer of doped LaCrO{sub 3} particles. It comprises providing LaCrO{sub 3} particles doped with an element selected from the group consisting of Ca, Sr, Co, Ba, Mg, and mixtures thereof; uniformly dispersing the particles in a solvent to provide a homogeneous dispersion; wet screening the dispersion to provide particles in the range of from 30 micrometers to 80 micrometers; admixing a fugitive polymer with the particles in an amount to provide homogeneous dispersion with a volume ratio of polymer plus particles:solvent of between 50:50 and 30:70 and a volume ratio of polymer:particles between 65:35 and 50:50; casting the dispersion onto a substrate, to provide a film having a wet thickness of from 80 micrometers to 150 micrometers; drying the film; and stripping the film from the substrate, to provide a particle-fugitive polymer film.
