Polycrystalline silicon carbide, for instance, exhibits an excellent load-bearing capacity at 2000 C and is helium tight at 1600 C. No other known material comes close. The use of these materials will certainly grow; however, the growth will be relatively slow and evolutionary in nature, because most of the appliions will serve new developing technologies.
