Paper Title:
Al2O3-Reinforced Feldspar Ceramic Composite Material
  Abstract

This paper focused on the properties of Al2O3-rainforced feldspar dental ceramic. The results indicated that the introduced Al2O3 could elevate the density of the sintered feldspar ceramic, where the relative density reached 97.9% under the conditions of 20 wt% Al2O3 additive and 1200°C. On the other hand, Al2O3 additive could remarkably promote the machinability and the ultimate bending strength of the modified feldspar ceramic. The grinding efficiency increased by 260.1% if the content of Al2O3 additive was 5 wt%, while the ultimate bending strength enhanced under increasing Al2O3 additive content. The microstructure analysis revealed a composition of α-Al2O3 as the dominant phase and crystalline calcium aluminum silicate hydrate as the minor phase in the Al2O3-rainforced feldspar ceramic. The feldspar represented totally as glass phase, wherein the Al2O3 grains showed a homogenized dispersion.
