Synthesis of Lanthanum Silicates with Apatite-type Structureby Atmospheric Plasma Spraying

摘要

The emergence of lanthanum silicate as an electrolyte isrequired to accelerate the development of synthesis techniquesfor intermediate temperature solid oxide fuel cells (ITSOFCs).Apatite-type oxide powders of La10(SiO4)6O3 havebeen elaborated through atmospheric plasma spraying (APS)using micro-scale mixtures of La2O3 and SiO2 powders.Granulometer and scanning electron microscopy analyseshave indicated the result of high temperature reaction andrapid solidification in the evolution of multi-scalemicrostructure.
