Progress in Natural Science:Materials International 2016年第1期26卷 41-48页

作者： Rehana Zia Madeeha riaz Nida ul nasir Farhat Saleemi Zora Kayani Safia Anjum Farooq Bashir Tousif Hussain Department of Physics Lahore College for Women University Government College for Women University CASP Government College

The main objective of the study was to control the degradation rate of material at a higher degradation rate improving the chemical stability of the material. Ta is known to have good chemical resistance, biocompatibility and show no adverse biological response. In the present study, Si O2–Na2O–Ca O–P2O5bioceramics with different Ta2O5contents was prepared by solid state sintering method at 1000 °C. The as-sintered ceramics were subjected to immersion studies in stimulated body fluid（SBF） for 21 days under static condition and characterized by XRD, FTIR, SEM, and AAS. The findings of the research indicate that the addition of Ta2O5controlled degradability, and all samples showed sufficient bioactivity.
