Effect of alumina (Al2O3) addition on the calcium fluoroaluminosilicate based bioglass ceramics derived from waste materials

Bioactive glass (BG) is well known as materials that have ability to form hydroxyapatite layer (HA) that accelerates bonding between bone tissues indicating a good biological response. However, previous BG with composition of SiO2-CaO-Na2O-P2O5 system exhibit lower mechanical strength. Current study...
