HEALTH MATERIAL AND PROCEDURES FOR THE PRODUCTION OF A SOCIAL

摘要

A thermochemically stable oxidic thermal insulating material presenting phase stability, which can be used advantageously as a thermal insulating layer on parts subjected to high thermal stress, such as turbine blades or such like. The thermal insulating material can be processed by plasma spraying and consists preferably of a magnetoplumbite phase whose preferred composition is MMeAlSUB11/SUBOSUB19/SUB, where M is La or Nd and where Me is chosen from among zinc, the alkaline earth metals, transition metals, and rare earths, preferably from magnesium, zinc, cobalt, manganese, iron, nickel and chromium.
