Ceramic heat spreaders for mosfets

[barber02]

I get amps in from time to time with ceramic heat spreaders.

Other than being extremely fragile, how well do they work in your opinions?

How do they work, in what way?

I think the brittleness is the only issue. They're excellent at heat transfer, IIRC.
