"GB/T 45009-2024 Rare earth environment barrier coating materials, ytterbium silicate powder" stipulates the technical requirements, test methods, inspection rules and labels, Encasement, transportation, storage and other contents of ytterbium silicate powder. The standard applies to ytterbium silicate powder prepared with ytterbium oxide and silicon oxidation as raw materials, which is mainly used for environment barrier coatings for engine blades of aviation, aerospace, automobile and large thermal power generation equipment. Ytterbium silicate powder has excellent high temperature Stability, thermal shock resistance and high temperature oxidation performance, making it a reliable high temperature protective coating material. The release and implementation of the standard will regulate the production and application of this material, promote the development of rare earth-based environment barrier coatings in our country, and break the blockade of foreign technologies.
