above reason. Si/Al ratio confirms the structure of sialate link as (Sialate- Di Silaxo-D20), (Silate Silaxo-D40), (Silate Tri Silaxo-D60), (Silate Silaxo-D80) and (Silate Tri Silaxo-D100). Si/Al ratio of 1 indicates that the structure is Sialate Silaxo, Si/Al ratio of 2 indicates that the structure is Silate Di Silaxo and Si/Al of 3 represents that it is Silate Tri Silaxo.
