(IIRC, really hard things like ceramics can't be cut because of surface fracturing or something.)That can happen, but the biggest reason is when the ceramic is harder than the cutting tool.

Very hard materials which are tough, like high-alloy steels, are perfectly cuttable without fracture problems--provided of course that the cutter is harder than the cuttee. As it were.
