Thermal Properties of Alkaline Earth Oxides
The heat capacities of MgO, CaO, SrO and BaO, reported in part I have been analysed in terms of the frequency spectrum of the lattice with the assumption that the effect of anharmonicity of the lattice may be neglected for T (@D / 3 ) . Following the usual procedure the n-th moments of the frequency spectrum with n = — 3, —2, — 1, 0, 1 to 6 were calculated from the experimental data. From the l...
متن کاملNon – Nominal Value of the Dynamical Effective Charge in Alkaline – Earth Oxides
We calculate ab–initio the electronic states and the Born dynamical charge Z of the alkaline–earth oxides in the local–density approximation. We investigate the trend of increasing Z values through the series, using band–by–band decompositions and computational experiments performed on fake materials with artificially–modified covalence. The deviations of Z from the nominal value 2 are due to t...
متن کاملSPECIATION AND LOCAL STRUCTURE IN ALKALI AND ALKALINE EARTH SILICATE GLASSES: CONSTRAINTS FROM 29Si NMR SPECTROSCOPY
‘?Si NMR spectroscopy provides important contributions to the understanding of silicate glass structure. as the resonance frequency is sensitive to several aspects of the local chemical environment (including intertetrahedral bond angles. bond distances. and number of bridging oxygens per silicon atom). New data on a series of binary alkali and alkaline earth glasses are presented which highlig...
متن کاملSOlt POTASH-POTASH INVESTIGATION-POTASH DEFICIENCIES
It is in this connection that it becomes very difficult at times for the agricultural scientist and practical agriculturist to meet on common ground, for very often a popular version of scientific reasoning may appear ambiguous, and in this case it would appear better to sacrifice the facile version (since the layman can always get an interpreter to explain if he is sufficiently interested) tha...
متن کاملDensity Functional Theory Study of Surface and Bulk Nitrates of .-Al2O3 Supported Alkaline Earth Oxides
Introduction Alkaline earth oxides (AEOs) such as BaO have received considerable attention for their application in the lean-burn engine NOx storage/reduction (NSR) technology [1]. Previous experimental investigations have indicated that barium nitrate is the most stable form of the stored NOx in Ba-containing NSR catalysts. Two distinctive types of barium nitrates, Ba(NO3)2, i.e. “surface” and...
