Light hardening dross for stereolithographic production of dental ceramics

摘要

A slip comprises (wt.%): (A) polyreactive binder (5-65), (B) photoinitiator (0.001-1) and (C) surface-modified ceramic and/or glass ceramic particles (35-90), in each case relative to the overall mass of the slip. An independent claim is included for preparation of a ceramic or glass ceramic molding involving: (a) preparing a green body by curing the slip by local introduction of radiation energy with formation of the geometric shape of the green body; (b) then subjecting the green body to a debinding heat treatment to remove the binder, in order to obtain a white body; and (c) sintering the white body.
