Abstract: Rare earth elements (Y, La, Ce, Nd, Gd and Dy) encapsulated by carbon nanocapsules (CNCs) were synthesized and their purity and air oxidation stability were estimated. The purity was estimated as the rare earth carbide content. Gd- and Dy-encapsulating CNCs had higher than 30wt% and others 15 to 20wt%. Encapsulated rare earth carbide was oxidized by heating in air at 400oC or higher. This suggested oxidation damage to the graphene capsules of CNCs.
