The role of alumina in aluminoborosilicate glasses for use
The role of alumina in aluminoborosilicate glasses for use in glass–ionomer cements not only through leaching of Al 3 ions from the glass into the cement matrix during formation but also through reinforcement of the resulting cement by the residual glass particles which have high alumina content and confer greater mechanical strength.
