Question:

Whats lighter and better? Ceramic or Carbon Ceramic?

I‘m doing this for another research project and I need to know if ceramic or carbon ceramic is better for high mechanical performance reasons. Or are they basically the same thing?

Answer:

you at the instant are not meant to tow a automobile a quantity miles on that is stress wheels. It chefs the transmission fluid. in case you ought to tow some distance, use a cradle. you like a rebuilt transmission. examine the backside of website 37.
If I had to chose one, I'd go with what you're calling Carbon Ceramic, which I imagine is also Carbon Fibers. It's much lighter than most ceramics and can stand very high Ts, equal or better than most inorganic ceramics. One of the disadvantages could be the electrical conductivity: the C-fibers tend to be somewhat electrically conducting, as its structre is similar to graphite, like a HUGE number of aromatic rings, similar to benzene, conected through their pi (highly delocalized) electron system. The other possible disadvantage is the synthesis method, involving quite a bit of chemistry, polymerization, and graphitization processes, heating to very high T ( 1,500oC) under controlled atmosphere (no O2 please). Engineers and physicists do not like much chemical processing. The inorganic ceramics tend also to be quite brittle, do not stand much mechanical shock. But there may be methods to improve it a bit. AlN, BN, Al2O3, ZrO2, SiC, SiN, and some of their combinations, are examples of inorganic ceramics. In the end the choice will really depend on the application and the cost - benefit balance.
