An Al-free glass-ionomer cement with good workability and setting behavior was obtained by mixing CaO-Fe2O3-SiO2 glass powder with polyacrylic acid solution. The cementation was speculated to proceed via the release of Fe3+ and Ca2+ ions from the glass, and subsequent formation of Fe (III) and Ca (II) polyacrylates.
