Effect of CaF2 and Na2SiF6 nucleating agents on the crystallization behavior and properties of MgO-Al2O3-SiO2 glass-ceramics

Impacts of substituting magnesium with zinc on crystallization behaviors in an aluminosilicate glass

“…To alter the nature of exclusive surface crystallization in the stoichiometric cordierite composition (2MgOÁ2Al 2 O 3 Á 5SiO 2 ), extensive research has focused on nucleating agents, such as TiO 2 , ZrO 2 , CeO 2 , or P 2 O 5 . [7][8][9] These nucleating agents were added to realize controlled volume crystallization and to induce the microstructural formation of a finely dispersed crystal phase into the glass matrix.…”
