Yttrium aluminate also has excellent creep resistance at high temperatures, high oxidation resistance, high thermal conductivity and good thermal stability. The creep rate of the oxides produced at IBU-tec is 2.5 × 10-9 %/s at 1,700 °C and 100 MPa, which is 1/10 of the creep rate of single-crystal Al2O3 under similar conditions. From this high creep resistance, yttrium aluminum oxide powder can find application as a material for the production of high temperature composite materials.

IBU-tec has experience in the development and production of yttrium aluminate powders. Thus, powder materials with different phase compositions can be provided, which can be used for bulk material as well as for phosphorescent phosphors.
By doping the oxides, the properties of yttrium aluminate ceramics can be significantly modified, opening up applications in lighting technology, laser technology, optoelectronics and also as jewelry stones.
