Abstract
A device operable in a temperature environment in excess of about 1000° C. is provided. The device comprises a substrate and a ceramic thermal barrier layer deposited on at least a portion of the substrate. The layer is formed with a ternary or pseudoternary oxide having a pyrochlore or perovskite structure and a fugative material and having pores or other voluminous defects. The thermal barrier layer advantageously is abradable.
