| It is virtually a compound of the two oxides, aluminum oxide and magnesium oxide. |
| The metallic oxide combines with this excess of acid anhydride, forming a mixed salt of metaboric acid. |
| It is composed of silica, alumina, carbonate of lime, magnesia and oxide of iron. |
| Two methods were used to determine, in non-isothermal conditions, the sintering activation energy of UO2 and UO2+x oxides. |
| The ash of beneficiated materials was richer in the basic oxides, while poorer in quartz. |
| Chemical behavior, such as the acidic or basic properties of oxides, is also periodic. |
