Effect of CaO additive on sintering and crystallization behavior of cordierite glass–ceramic prepared by sol–gel method
Source abstract
Abstract
In the present work, cordierite glass–ceramic was prepared via sol–gel method using TEOS, AlCl3·6H2O, MgCl2·6H2O as starting materials. Different steps of phase transformations to cordierite have been studied by DSC and XRD. Various phases have been formed at different heat-treatment temperatures. Addition of CaO led to an increase in both the formation rate and the intensity of α-cordierite. Sinterability of the samples was determined too. The results showed that high content of CaO improved sintering. Morphology of hexagonal prism for α-cordierite was displayed by SEM.
