摘要
The role of solid state epitaxy in the crystallization of nanocomposite cordierite glass to glass ceramic was investigated. The use of isostructural (alpha-cordierite) seeds in cordierite glass led to a lowering in the crystallization temperature to form glass ceramic by about 50-degrees-C compared to the unseeded glass. The use of non-isostructural seeds such as ZrO2 and TiO2 did not lower the crystallization temperature of cordierite glass to glass ceramic, and in the case of the TiO2-seeded glass the crystallization temperature increased by about 50-degrees-C compared to the unseeded alpha-cordierite glass. The lowering in crystallization temperature by alpha-cordierite seeding can be attributed to the nucleation and epitaxial growth mechanism.
