We'd need more information to go on to answer any of your questions. I have seen 510 atomizers with a ceramic heating element some time ago (might have been the AVA atomizers, I can't recall), though they didn't last long on the market as far as I know. There are also ceramic heating elements (google "vaping donuts" and you'll probably find them) for use in RDAs that have been around a while, but I'm not sure how widely used they are anymore. It wouldn't surprise me if there was a new ceramic option available now
