We used diamond belts here Sharpco and have manged to get under 200. We quit there. We think that most ceramic edges come in at 300 or higher for a reason and its not because the manufacturers can't get them any sharper. It's because they're too fragile at anything below 300. In fact, they're fragile at 300. it's not like they won't serve their intended purpose but you have to be more careful than with steel and can't abuse the edges in any way.
One thing for certain in our experience - if you want to go sharper with ceramic and are using diamonds, the higher number diamond grits are the ticket - 1000 and above.
