Ceramics get hot, they just don't melt as easy
We have been being promised ceramic engine parts for over 40 years, yet they don't seem to show up in actual service engines (reciprocating, they do show up in turbines sometimes) except for certain applications. We have had ceramic insulators in spark plugs for decades
beats the heck out of mica.
One account claims an experimental engine with ceramic cylinder had trouble with pre-ignition at 12 to 1 compression ratio. Which tends to limit it's usefulness on a supercharged engine.
