As the physical properties of the final lanthanum cobalt oxide powder material obtained are strongly dependent on the method of preparation, the development of a convenient method for the synthesis of lanthanum cobalt oxide is also essential.
Lanthanum cobalt oxide polycrystalline powder was synthesized through optimized solid-state reaction method, because of advantage given by simplicity and the use of relatively inexpensive oxides as starting materials.
To elucidate the reproducibility of our fabrication technique, the variations in properties among the batch to batch samples were evaluated.
The prepared lanthanum cobalt oxide powder is essentially within a single crystalline phase. The results showed that we realized good reproducibility of batch to batch powder properties, which is one of the most important factors for commercialization.
