    ceramics.onlinelibrary.wiley.com/doi/pdf/10.1111/jace.15498 Merwinite has a monoclinic crystal structure and is recog-nized as a relative of b-C 2S that is made by partially replac-ing one of the Ca2+ sites in b-C 2S with Mg 2+ ions, while the SiO 4 configuration in Ca/Mg trigonal prisms of merwinite is somehow more ordered than that in b-C 2S. Although b-C 2S is formed only as a metastable phase ...
