Preparation and characterization of novel tricalcium silicate bioceramics

Novel tricalcium silicate (Ca3SiO5) ceramics were successfully fabricated. The mechanical properties of the ceramics were dependent remarkably on sintering temperature. The fracture toughness, Young's modules, and bending strength of Ca3SiO5 ceramics sintered at 1500 degrees C were 1.93 MPa center dot m(1/2), 36.7 GPa, and 93.4 MPa, respectively. These findings suggest that the Ca3SiO5 ceramics possess good mechanical properties, and might be a potential bone implant material. (c) 2005 Wiley Periodicals, Inc.
