application of silicon carbide in semiconductor?

what are properties that different between silicon and silicon carbide which make them have different characteristic in semiconductor field?

Not really an answer, but I recall reading in Nature or Science or maybe Aviation Week/Space Technology between 10 and 15 years ago that some researchers had made a transistor of SiC that worked at 350C !

I would imagine that SiC is much harder to process and purify.
