摘要：

Crystallization kinetics of the cordierite-type (MgAl1.83Si2.25Oy) glass with the BaO addition (X molar ration) in the powder form has been studied by non-isothermal DTA. Formation of multiphase corresponding to various BaO content was investigated by X-diffraction technique. Addition of small amount of BaO (X less than or equal to 3%) to the cordierite-based glass could suppress the crystallization of the alpha-cordierite phase. Enstatite and hexacelsian phases were the predominant phase with the increase of BaO content in the range of 3% < X < 8% and X greater than or equal to 8%, respectively. (C) 1998 Elsevier Science S.
