Abstract
Thermal treatment and the addition of lithium influence the surface ar ea of the oxides SiO2, Al2O3 and MgO. A calcination temperature greate r than or equal to 1073 K causes a significant decrease of the surface area of SiO2 and Al2O3; the same is not observed in case of MgO. Syst ems Li/MgO and Li/SiO2 are characterized by a much smaller specific su rface area than pure oxides thermally treated at the same temperature.
