No other director emerged on the world scene in the Fifties with the impactfrom MAS NMR is indicative of the type of chemical species present in the glass. The 29Si MAS NMR spectroscopy showed that Bioglass 45S5 was a Q2 type-structure with a small amount of Q3 ; i.e., silicate chains with a few crosslinks. The 31P MAS NMR revealed predominately Q0 species; i.e., PO43−; subsequent MAS NMR spectroscopy measurements have shown that Si-O-P bonds are below detectable levels

Compositions 
There have been many variations on the original composition which was Food and Drug Administration (FDA) approved and termed Bioglass.  This composition is known as 45S5. Other compositions are in the list below.
45S5: 45  wt% SiO2, 24.5 wt% CaO, 24.5 wt% Na2O and 6.0  wt% P2O5. Bioglass
58S: 58 wt% SiO2, 33 wt% CaO and 9 wt% P2O5.
70S30C: 70 wt% SiO2, 30 wt% CaO.
S53P4: 53 wt% SiO2, 23 wt% Na2O, 20 wt%
