Description
In the field of ancient ceramics study, several advanced characterization techniques including XRD refinement, Raman mapping, TEM-EDS, SEM-EBSD, SR-based XAS and Mössbauer spectroscopy etc. firstly combined with theoretical calculation based on Density Functional Theory (DFT) to develop a novel strategy for providing detailed structural information and giving the most stable structural models of crystals, thus, our work would enlighten the deep-going and systematic investigation of the ancient ceramics. A major breakthrough has been achieved in this work for proving high-alumina clay introduced Al in glazes, which doped Al into ε-Fe2O3 lattices and thus stabilized the metastable polymorph. This work deepened the understanding of high-alumina, high-calcia, high-fired glazes and their subtle firing manipulation technology, which would lead to inspiration to the new field in materials synthesis.
