A Vision System is the first thing that comes to mind. Cognex is the industry leader.

For chips, vision sounds like a good way to go.

For cracks and internal defects a sonic system my be good. If your parts are all the exact same size and shape you can just measure the resonant frequency and compare to a ref. part. I have seen the systems, but can't remember the name right now.

Here is a report that I ran across from ONRL. You might also want to check their website, Ceramic Technology for further information.
