| Development of silicon carbide for extreme application | |
| Program: | SRDA |
| Project leader: | Ing. Hanzel Ondrej, PhD. |
| Annotation: | The proposed project is oriented towards development of fully dense silicon carbide ceramics without traditional oxide sintering additives or with addition of trace amount of metals (Al, Fe) at sintering temperature lower than temperature (T < 2100°C) required for preparation of solid-state sintered SiC. Project will be focused on comprehensive understanding of sintering mechanisms and study how modification of silicon carbide powders and/or addition of very small amount of metals (Al, Fe) can possibly influence and lower sintering temperature for preparation of fully dense silicon carbide. Due to the increasing interests and demands in energy applications, atmospheric re-entry vehicles, propulsion-system components, aerospace applications, parts of rocket engines, etc. is inevitable also characterize high-temperature properties (thermal conductivity, high-temperature strength, oxyacetylene torch resistance) of prepared silicon carbide ceramics. So, thermal conductivity up to 1500°C, high-temperature strength in temperature range 1500 – 2000°C and oxyacetylene torch resistance at temperature higher than 1700°C will be investigated and effect of powder modification, sintering parameters and microstructure on high-temperature properties will be studied and evaluated |

| Development of new compositionally-complex ceramics for extreme applications | |
| Program: | SRDA |
| Project leader: | Ing. Tatarko Peter, PhD. |
| Annotation: | The main aim of the proposed project is to develop next generation ultra-high temperature ceramics capable of withstanding temperatures up to 3000°C for propulsion systems, rocket engines and other aerospace applications. This will be achieved by the synthesis of diboride ceramics with unique compositionally -complex structures, comprising of at least five metal elements. A systematic study will be conducted to generate new knowledge on the understanding of the effect of various molar ratios of individual metal cations in diboride structures on the stability, synthesis, sintering and mechanical properties of bulk diboride ceramics. The results will significantly contribute to the expansion of the high entropy ceramics concept with equimolar compositions towards the development of compositionally-complex ceramics with non-equimolar compositions. The project also proposes an innovative way of manufacturing ultra-high temperature ceramics, consisting of the development of ceramic composites based on the high-entropy and compositionally-complex diboride matrix, reinforced with the refractory additives. The output of the project will be new fundamental knowledge on the formation of disordered diboride structures, and their effect on mechanical properties of the materials at room, intermediate, and ultra-high temperatures. |
