Among different silicate systems, CaO−MgO−SiO2 is the one of most promising due to abundance reagents, easier fabrication, improved performance, and wide range application. Analysis current literature sources denotes that phase diagram system regularly used by researchers worldwide as constitutive model for synthesis glass-ceramic materials (GCs) possessing an adequate combination high chemical...

Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the result of alkali activation. The alkali activation of a Ca-Mg silicate glass (with a composition close to 50 mol % wollastonite-50 mol % diopside, w...

Although pyroxene has been detected remotely across the Solar System, limited information is available from infrared remote sensing about Mg-Fe composition of pyroxene, and distinguishing between augite (20 < CaSiO3 45) diopside-hedenbergite (CaSiO3 > remains challenging. The characteristics in intermediate range (4–8 μm), meanwhile, have not documented. Using reflectance spectra 72 samples ran...

A metamorphosed lithic clast was discovered in the CM chondrite Grove Mountains 021536, which was collected in the Antarctica by the Chinese Antarctic Research Exploration team. The lithic clast is composed mainly of Fe-rich olivine (Fo62) with minor diopside (Fs9.7–11.1Wo48.3–51.6), plagioclase (An43–46.5), nepheline, merrillite, Al-rich chromite (21.8 wt% Al2O3; 4.43 wt% TiO2), and pentlandit...
