Abstract
The current work examines the structural and biological characteristics of doped Zn, Mg, and Sr. Na2O–CaO–Si2O–P2O5 silicate ceramics synthesized by the solid state method. The undoped sample showed amorphous behavior after sintering at the 800 OC while doping of SrO, MgO and ZnO induce crystal growth; and a single phase of Parawollastonite (JCPDS# 00-043-1460) was identified in both doped samples. The strontium doped sample showed the highest value of the dielectric as compared to other three samples. The Sr doped sample had higher dielectric value because the size of Sr2+ is greater than Ca+2 so it will possess the higher polarizing power. Conductivity of Zn and Sr doped samples increased with increase in frequency and Mg doped decrease with increase in frequency. Bioactivity test confirmed that doped samples were more bioactive as compared to undoped samples, and Sr doped sample showed superior bioactivity as compared to other samples.
