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.
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.

Silicon carbide (SiC) nanoparticles exhibit characteristics like high thermal conductivity, high stability, high purity, good wear resistance and a small thermal expansion co-efficient. These particles are also resistant to oxidation at high temperatures.
To manufacture Reaction Bonded Silicon Carbide (RBSC), Silicon is infiltrated into a pre-formed silicon carbide/carbon powder green body which is then fired. This gives rise to around 10% free silicon, which fills the pores. The resulting microstructure has low

Silicon carbide is deposited as thin layers on carbon fiber-reinforced carbon by CVD (chemical vapor deposition). Deposition takes typically place at temperatures of 1,200-1,300 °C. The thermal expansion behavior of the substrate material should be adapted to the SiC coating to minimize thermal stresses.
Its thermal conductivity is 3.5 times better than silicon. It can be heavily doped for high electrical conductivity, yet on the other hand can sustain high electric field strength without experiencing breakdown. In addition to operating up to high temperatures it is also

Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring.
