Description
Summary:The developmental of composites as dental coating materials is growing rapidly. To increase mechanical, physical and aesthetical properties of dental coating materials, has been developed composited dental based on ceramic matrix composites. Only a few ceramic biomaterials that are suitable for this dentistry i.e. zirconia (ZrO2) and alumina (Al2O3). Zirconia and alumina-based ceramic present interesting properties for their application such as a dental coating material. Zirconia was used as the matrix, extracted from natural zircon sands Kereng Pangi, Central Kalimantan and alumina powder were used as the filler. In this work, influence of ZrO2 composition on ZrO2/Al2O3 ceramic composites that using 100, 70, 60weight% zirconia was characterized. Powder of ZrO2 and Al2O3 were mixture by planetary ball milling for 3h at 150rpm. Homogeneous of composites can be affected from speed and duration of stirring. The homogeneous of filler and matrix can be improved mechanical properties of composites. Powder mixtures were pressed under 80MPa pressure. Characterization FTIR and XRD were used to confirm the absence of any new phase and the composites were formed. The FTIR analysis showed that no new compounds are formed between ZrO2 and Al2O3. This result can be correlated with the XRD pattern of ZrO2/Al2O3.
