Development of TiB₂ -MoSi₂ composites for high temperature applications

In the development of non-oxide ceramics, like borides, with desired properties, the selection of type and amount of sinter-aid as well as the sintering conditions are important aspects of consideration. The present contribution reports the optimization of hot pressing temperature and amount of MoSi₂ (0-10 wt. %) for achieving full densification of TiB₂ materials. While the consolidation of the materials has been pursued using hot pressing technique, the microstructure of the obtained materials is characterized using XRD and SEM-EDS. Based on the obtained experimental results, it can be concluded that the newly developed TiB₂-2.5 wt. % MoSi₂ materials can be considered for high temperature structural applications
