Effect of MgO on the structure of SiO₂‐poor/rich MgO‐CaO‐SiO₂ melts by in situ high temperature time‐gated Raman spectroscopy and theoretical calculation

Abstract

The effect of MgO on the microstructures and macroscopic properties of SiO 2 -poor/rich MgO-CaO-SiO 2 melts was investigated by in situ high temperature time-gated Raman spectroscopy coupled with aerodynamic levitation heating of molten samples. Results of density functional theory calculations of

Operandotime-gated Raman spectroscopy of solid catalysts

“…Kerr-gated Raman spectroscopy (KG-RS) has been applied for the study of carbonaceous species on solid catalysts, including the formation of coke species during the MTO reaction 22 and carbon deposits on other strongly fluorescent zeolite-based catalyst materials, 23,24 as well as in battery research. 25,26 CMOS-SPAD-based time-gated Raman spectroscopy was used for numerous different type of samples, including biological samples and pharmaceuticals, [27][28][29][30][31] rareearth-element containing rock samples, 32 high-temperature melts, 33 and pickle liquor. 34 Precisely assessing the beneficial effect of time gating on spectral quality remains challenging.…”
