Ceramics have a ceramic surface that lasts the life of the rim. They are very good in the wet but you need to use the specific brake pads to get good performance. They are great for really sloppy conditions that eat rims.
Mine are CDs which you can see in the shot I posted above. I have been riding them off and on since about 1991. Most of the anodizing still remains. I have only worn through in sections and that was only accelerated during cross season.
