| 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 |
