This material was prepared in-house and the results of an oxidation study in the range 1273 K to 1648 K are discussed. The results were compared to those of monolithic Nd-N-apatite and a HIPped Si3N4 with only a nominal amount of Y- and Al-Based intergranular phase. }, title = {A Comparison between the Oxidation Behaviour of Silicon Nitride Hot-Pressed with Neodymium Oxide and a HIPped Silicon Nitride.}, type = {}, url = {}, volume = {}, number = {}, journal = {Journal of the Electrochemical Soc.}, pages = {}, issn = {}, publisher = {}, doi = {} }
