Modification of the surface of nanostructured Bi0.95La0.05FeO3 ceramic by plasma

Abstract

Nanostructured ceramics of the composition Bi0.95La0.05FeO3 were fabricated, and the structure was studied before and after exposure to an argon plasma flow at a temperature of ∼ 600 °C for ∼ 30 minutes. Plasma treatment of the surface, with a positive effect of the formation of a monolithically conjugated structure and an increase in the size of grain crystallites, leads to a decrease in the proportion of the main phase on the surface to ∼70%. It has been established that compaction is up to ∼30% of the sample thickness.
