Kurzbeschreibung (Abstract)
In this work, a lutetium-modified silicon oxycarbide (SiOC) glass ceramic was prepared from a single-source precursor via pyrolysis and subsequent hot pressing. It is shown that the main crystalline phase in the hot-pressed SiLuOC is Lu2Si2O7. The high-temperature (HT) creep behavior of SiLuOC was assessed by compression creep experiments performed between 1100 and 1300°C at constant true stresses between 25 and 75 MPa. The calculated viscosity values of SiLuOC were found to be significantly higher as compared to those of SiRE(Al,Mg)ON glasses (RE = rare earth elements). Thus, the presented SiLuOC-based glasses might be used as alternative sintering aids for the liquid-phase sintering of HT creep resistant Si3N4 monolithic samples.
