摘要：
Slip based on a polyreactive binder, polymerization initiator and filler, which contains (A) 5-65 wt.-% polymerizable binder, (B) 0.001-1.0 wt.-% photoinitiator and (C) 35-90 wt.-% surface-modified ceramic and/or glass ceramic particles relative to the overall mass of the slip, and process for the preparation of ceramic mouldings by rapid prototyping processes using the slip.
