Heat insulator and application of the same

摘要

A heat insulation material consists of a first basic component that is fully- or partly stabilised zirconium dioxide, a perowskite with a high melting point, a ternary oxide in pyrochlor- or defect-fluorite structure or a complex oxide in magneto-plumbate-structure, and a second sintering agent with 0.5 to 10 Wt. % with respect to the components of silicon, boron, lithium or beryllium.
