TL;DR: In this article, a double peak in the 1430-1515 cm y1 3 region in the FT-IR spectrum, attributable to the CO 2y group, showed that carbon dioxide is 3 present in the ground diopside, in the same form as in synthetic and natural silicate glasses after dissolution of CO at high temperatures and pressures relevant to the magma state.

TL;DR: In this article, the authors used diffuse reflectance Fourier transform infrared spectroscopy (DRIFT), powder X-ray diffraction, 29Si MAS-NMR spectrograms, CO2-content analysis, and surface area measurements to study the carbonization process of the ground mineral enstatite MgSiO3.

TL;DR: In this paper, a planetary ball mill of natural diopside CaMgSi2O6 and plagioclase (CaAl2Si 2O8)0.745·(2NaAlSi3O8),0.209·( 2KAlSi 3O8 )0.046 in CO2 atmosphere has been studied and the results on thermal relaxation of the activated samples were reported.

TL;DR: In this paper, the carbon dioxide consumption of titanite during dry grinding in air has been studied and the following sequence concerning carbon dioxide sorption ability was revealed: enstatite, enstatites MgSiO3, diopside, akermanite Ca2MgSi2O7, and wollastonite CaSiO5.

TL;DR: In this paper, the IR spectra of ground minerals contain bands of distorted carbonate groups due to absorption of carbon dioxide due to a prolonged grinding of diopside, akermanite, sphene, wollastonite, and enstatite.
