The Pros & Cons of Advanced Ceramics | Better MRO
Silicon carbide matrix/silicon carbide fiber CMCs for high-temperature appliions demand high-purity fibers, with prices starting at over $4,000/lb, leading to preform prices of over $9,000/lb.” Experts note ceramic adoption has been slow and often backed by subsidies and incentives from government funding, so to really take off, cost does need to come down.
New processing methods to produce silicon carbide and …
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.
