Research on dental ceramics by Spark Plasma Sintering

Guanglei Zhang

Abstract

The feldspar dental ceramics were prepared by Spark Plasma Sintering (SPS). In the experi-ment the effects of sintered technology on the property of the sintered sample were investigated. The results show that a high density feldspathic ceramic is realized, the value of fracture toughness reachesabove 1.4 MPa·m1/2, which was hot-pressed at 1120-1300℃and 30MPa, with a 100℃/min rate.
