YbAlO3

Ytterbium aluminum oxide (YbAlO₃) is a rare-earth ceramic compound belonging to the perovskite family, valued for its thermal stability and refractory properties at elevated temperatures. It is primarily investigated as a thermal barrier coating material and in high-temperature structural applications, particularly where resistance to thermal cycling and chemical corrosion is critical; its rare-earth composition makes it notably more expensive than conventional alumina or zirconia alternatives, so selection depends on demanding thermal or chemical environments where conventional ceramics fall short.
