Abstract For inert matrix fuels, SiC and BeO represent two possible matrix phase compounds that exhibit very high thermal conductivity, high melting points, low neutron absorption, and reasonably high radiation stability. BeO is chemically compatible with UO 2, PuO 2 and Zircaloy to very high temperatures, but SiC reacts with all three at somewhat lower temperatures.
Overview of Silicon Carbide
Silicon carbide, SiC, is a very hard and strong non-oxide ceramic that possesses unique thermal and electronic properties. With strengths ranging from 15 GPa in polycrystalline bodies up to 27 GPa in SiC single crystals and its excellent creep resistance, silicon carbide also lends itself to many high-temperature mechanical appliions.
