Coulomb Complexing and the Solubilization of Oxides in Halide Melts

Complexing of Al+3 by S–2 Ions in Alkali Halide Melts

Continuous pressure-induced structural transition in the noble-metal halide melts.

The reduction of the charge of the species in molten salts, including the complete removal of the Coulomb interaction, appears to have the same eFect as an increase in the pressure on these systems. This observation leads to the prediction that a continuous pressure-induced structural change is to be found in the noble-metal halide melts at much lower pressures than those used to induce a simil...

Electrical Conductivity Measurement of Oxides Melts

Notwithstanding on variety of existing processes of induction skull melting of oxides, electrical and thermal properties of oxides melts are practically unknown. From the other hand, liquid-phase synthesis of Hi-Tech oxides materials such as new ceramics, monocrystals and glasses, requires knowledge of melts properties up to 3700 K. Inasmuch as the main physical property, which influence to the...

Organic-Inorganic Hybrid Compounds Based on Lead Halide Units: Preparation from Melts and through Grinding Effects

Organic-inorganic hybrid compounds based on lead halide units of the formula (CH3NH3)2(CH3C6H4CH2NH3)2Pb3(BrxY1−x)10 (Y = Cl, I) were prepared from melts, and their optical absorption as well as photoluminescence spectra, before and after grinding the compounds, were investigated. The luminescence of the materials after grinding is strong and is observed with naked eye. By changing the mole fra...

The origin of the conductivity maximum in molten salts. II. SnCl2 and HgBr2.

The phenomenon of electrical conductivity maxima of molten salts versus temperature during orthobaric (closed-vessel) conditions is further examined via ab initio simulations. Previously, in a study of molten BiCl3, a new theory was offered in which the conductivity falloff at high temperatures is due not to traditional ion association, but to a rise in the activation energy for atomic ions hop...
