La0.99Sr0.01CoO3

ceramic

La0.99Sr0.01CoO3 is a strontium-doped lanthanum cobalt oxide, a mixed ionic-electronic conductor (MIEC) ceramic belonging to the perovskite family. This is a research-phase material designed for high-temperature electrochemical applications where oxygen transport and electron conductivity must occur simultaneously. The material is notable for its potential in solid oxide fuel cells (SOFCs) and oxygen separation membranes, where the partial substitution of strontium into the lanthanum cobalt lattice enhances ionic mobility while maintaining electronic conduction—offering a balance not easily achieved in undoped alternatives.

La0.9Bi0.1NiO3

ceramic

La0.9Bi0.1NiO3 is a doped perovskite ceramic compound in which bismuth partially substitutes lanthanum in a nickel oxide lattice. This is a research-phase material, part of the broader family of rare-earth nickelate perovskites being investigated for solid oxide fuel cells (SOFCs), oxygen permeation membranes, and electrochemical devices where mixed ionic-electronic conductivity is valuable. The bismuth doping modifies the electronic structure and transport properties compared to undoped lanthanum nickelate, making it relevant for applications demanding enhanced oxygen diffusion or catalytic activity in high-temperature oxygen-deficient environments.
