Both ceramic and steel are ideal for certain types of coffee grinding, but ceramic is unique because it produces less heat during the grinding process. The best use for ceramic burrs is manual grinding.
Many people prefer a ceramic burr coffee grinder. Being made from ceramic means it can be used for a long time without ever wearing down. Ceramic coffee grinders are also easy to store, most people simply place it in a cabinet or pantry until they are ready to use it again.
