Abstract

The ZrO2-Mg-HA powders were fabricated by the chemical precipitation and pressureless sintering technology. The dental filling materials were prepared in combination with ZrO2-Mg-HA powders and polymethacrylate. The phase composition, fracture morphology and mechanical performance of the ZrO2-Mg/HA composites were investigated in details. The results showed that the introduction of moderate content of the ZrO2 was benefit to improve the compressive strength of the material. The investigated ZrO2-Mg/HA composites could meet the requirements for the dental filling materials.
