Abstract
The relation between the molar volume of metal oxides and their composition has been discussed. In order to compare molar volume of oxides with different compositions, the volume per one mole of oxygen atoms (Ma/bO) was used. It has been found that molar volumes of oxide phases of the same metal in the composition range 2 > a/b > 0.5 are linear functions of composition. This type of relationship has been proposed as an additional criterion to classify an oxide as a compact structure. Furthermore, in the case of oxides with metal ions in higher oxidation states (Mz+ > M4+) the increase of the molar volume (relative to the MO2 oxides) and the formation of framework structures have been found. Molar Volume and Composition of Oxides of the Same Metal Andrzej Stoklosa*, Barbara Laskowska Molar volumes of oxide phases of the same metal in the composition range 1>a/b>0.3 are linear functions of composition.
