Abstract

Thermal treatment and the addition of lithium influence the surface area of the oxides SiO2, Al2O3 and MgO. A calcination temperature ≥1073 K causes a significant decrease of the surface area of SiO2 and Al2O3; the same is not observed in case of MgO. Systems Li/MgO and Li/SiO2 are characterized by a much smaller specific surface area than pure oxides thermally treated at the same temperature.
