摘要
In the present invention, lanthanum nitrate hydrate (La(NO 3 ) 3 · nH 2 O, x is a natural number of 10 or less) powder, yttrium nitrate hydrate (Y(NO 3 ) 3 ·nH 2 O, x is 10 or less Natural water) mixing the powder and zirconyl chloride hydrate (ZrOCl 2 ·nH 2 O, x is a natural water of 10 or less) in a solvent to form a mixture, mixing the mixture with oxalic acid, and the mixture and the Adding a mixed solution of oxalic acid to the basic solution to form a precipitate, filtering and drying the precipitate, and calcining the dried product (La 1-x Y x ) 2 Zr 2 O 7 (0 x 1) relates to a method for producing a lanthanum zirconate-based powder for thermal barrier coating comprising the step of obtaining a powder. The lanthanum zirconate-based powder for thermal barrier coating produced by the present invention has low thermal conductivity, high chemical resistance and corrosion resistance, and is utilized as a thermal barrier coating material for gas turbine engines or internal combustion engines used at high temperatures. Can be.
