A thermal barrier coating material, which comprises, as a main component, a composition having an orthorhombic or monoclinic structure (for example, a tabular perovskite structure represented by the empirical formula: A2B2O7) derived from a perovskite structure or a tetragonal layer structure having a c axis/a axis ratio of 3 or more (for example, a K2NiF4 structure a Sr3Ti2O7 structure and a Sr4Ti3O10 structure), a composition represented by the empirical formula: LaTaO4, or a composition having an olivine type structure represented by the empirical formula: M2SiO4 or (MM~)2SiO4 wherein M and M~ are divalent metal elements. The thermal barrier coating material is novel, is free from problems of the phase transition and the like has a melting point higher than the temperature region for use, and has a thermal conductivity less than that of zirconia and a thermal expansion coefficient greater than that of zirconia.

L'invention porte sur un matériau de revêtement à barrière thermique qui comprend, comme composant principal, une composition possédant une structure orthorhombique ou monoclinique (telle qu'une structure tabulaire en perovskite représentée par la formule empirique : A¿2?B¿2?O¿7?) dérivée d'une structure perovskite ou d'une structure à couches tétragonales ayant un rapport axe c/axe a d'au moins 3 (par exemple, une structure K¿2?NiF¿4?, une structure Sr¿3?Ti¿2?O¿7? et une structure Sr¿4?Ti¿3?O¿10 ?; une composition représentée par la formule empirique : LaTaO¿4? ou une composition ayant une structure de type olivine représentée par la formule empirique : M¿2?SiO¿4? ou (MM')¿2?SiO¿4, ?dans laquelle M et M' sont des éléments métalliques divalents. Le matériau de revêtement à barrière thermique est nouveau, ne présente pas de problèmes de transition de phase et analogue, et a un point de fusion supérieur à la plage de températures à utiliser, et un coefficient de dilatation thermique supérieur à celui du zircone.
