Effect of Addition Nano Zirconia on the Physical and Mechanical Proper

45S5 bioglasses have been successfully used as bone graft materials in dental and orthopedic surgery but its poor mechanical strength limits its used in load-bearing applications, the approaches that has been used to strengthen the bioglass lead to decreased its bioactivity .Objective: Bio glasses with the composition of 45SiO2,24.5 Na2O,6 P2O5 , CaO ( 24.5- X), by varying zirconia content( X= 0,1,3 and 5 wt %) were synthesized via conventional melting technique. The main objective of the this work was to estimate the role of nano-mZrO2 in 45S5 bioglass system and study their effect on of 45S5 bioactive glass.
