I assume that toilet lids are ceramic to have the same durability and antiseptic properties as the rest of the toilet, and that they are made thick enough to not break if dropped.
There are probably other materials that would also work, though... I'd expect any material used for toilet seat lids (plastic, or coated wood composite) satisfies similar constraints.
Incidentally, ceramic can become razor-sharp when broken, so the article's suggestion of making lids easier to break carries its own set of risks.
