THERMAL BARRIER COATING MATERIAL |
摘要 |
<p>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.</p> |
