Direct Gel-Casting of Zirconia for Dental Application: Gelation Kinetics and Pyrolysis of Organic Additives

Abstract:

Article Preview

The gelation kinetics of two water-based gel-casting systems, made from reagents with very low acute toxicity, has been investigated. The zirconia particles greatly enhance the gelation rate, thus reducing both the temperature and time required for complete gelation. Binder burnout is complete and comparison of the pyrolysis of the net gel and the zirconia-based gel-cast parts revealed that the presence of zirconia particles accelerates the pyrolysis of the gel.
