| Program: | VEGA |
| Project leader: | Ing. Hanzel Ondrej, PhD. |
| Annotation: | The main goal of this project is preparation of dense silicon carbide (SiC) ceramics without sintering additives and/or silicon carbide composites with very low content (up to 1 wt. %) of sintering additives (oxides of rare-earth elements), with high thermal conductivity. The research will be focus on study of the effect of a-SiC and ß-SiC phase content on thermal conductivity of silicon carbide without sintering additives and the second research direction will be focus on study of the effect of amount and type of additives (oxides of rare-earth elements) on the thermal conductivity of SiC composites. In order to achieve project objectives, research focused on preparation of dense silicon carbide or SiC composite at relatively low sintering temperature (up to 2000°C) will be necessary. This process comprises study of SiC powders or SiC composite powders modification by freeze granulator, thermal annealing of granulated powders and followed by granules sintering with field assisted sintering technology (FAST). |
