Inorganic Materials Aims and scope

Abstract

We have studied the effects of the morphology and concentration of pore formers on the microstructure and gas permeability of porous zirconia-and lanthanum-gallate-based oxygen-ion-conducting ceramics. The results have been used to optimize the preparation conditions and composition of the ceramics. The resultant dense, fine-grained materials have porosities of up to }~56%.
