Sort of. There's ceramic in the coating, but it's a minor component. More specifically, the coating is referred to as sol-gel ceramic.

For example, premium PTFE coatings such as GMM's Duramax and Whitford's Eclipse are internally reinforced with hard materials of some sort. However these are not marketed as PTFE-free, because obviously they aren't. On the other hand, a ceramic coating that's advertised as PTFE-free, such as Thermolon (which is used in GreenPan) is completely free of fluorinated chemicals.
