The effect of TiO2, ZrO2 and P2O5 as nucleating agents was discussed in a SiO2-Al2O3-MgO-CaO-Na2O glass system. Crystallization study of glass system containing these oxides indicated that only surface crystallization and not volume crystallization occurred. The crystals that were formed were wollastonite and a small amount of diopside. It was found that these oxides suppressed surface crystallization and reduced the crystal growth rate. The reason for this suppresion was explained by the crystal growth theory. These oxides were considered to stabilize the glass system by incorporating into the glass network.
