Microstructural and hydration resistance study of CaO with powder surface modification by Al coupling agents: Alkoxy type and phosphate type

Fabrication and property evaluation of calcium-oxide-loaded microcapsules during supplemental heat-based exploitation of natural gas hydrates

“…The changes in the surface elemental composition in the different manufacturing processes correspond to the theoretical results obtained for the surface modification and layer-by-layer assembly process. 19,20…”

“…The changes in the surface elemental composition in the different manufacturing processes correspond to the theoretical results obtained for the surface modication and layer-by-layer assembly process. 19,20 The sample surface morphologies of CaO, 1R-CaO, and 3R-CaO fabricated using absolute ethanol as the dispersant were observed using SEM (Fig. 5).…”

“…The surface modication of CaO can help increase the exothermic duration from 25 to 75 min. [12][13][14] Since the 1980s, microencapsulation has been successfully applied to the pharmaceutical eld, followed by extensive application and development in the food, chemical, and textile industries. Microencapsulation can be applied to encapsulate active molecules to isolate and protect them, release them in a controlled manner, and improve their compatibility and dispersion.…”
