摘要: For oxides, MO (M = Mg, Ca, Sr, Ba), the basicity moderating parameter of M governs nature combined oxide(-II) ions, specifically (i) its Pauling electronegativity, x{sub 0}, and (ii) electronic polarizability, a{sub O{sup 2{minus}}}, so leading to a simple relationship between 0} 2{minus}}}. This is not obeyed by transition metal oxides Mn, Fe, Ni), but chemical behavior mixed molten oxide systems (slags) indicates that discrepancy lies in no It argued this arises because contribution heat formation M-M bonding these oxides. CdO metallic TiO VO are also considered.
