The atomic structural arrangements of liquid iron oxides affect the thermophysical and thermodynamic properties associated with the steelmaking process and magma flows. Here, the structures of stable and supercooled iron oxide melts have been investigated as a function of oxygen fugacity and temperature, using x-ray diffraction and aerodynamic levitation with laser heating. Total x-ray structure factors and their corresponding pair distribution functions were measured for temperatures ranging…

Reconsideration of Viscosity Variation Mechanism in Calcium Ferrite Melt During Isothermal Melting Process

Two hypotheses exist to explain the viscosity decrease mechanism of calcium ferrite (CF) melts during isothermal melting in air: variations in either the short-range structure near Fe3+ or the Fe

Evidence from X-ray absorption for network-forming Fe2+ in molten alkali silicates

Fe2+ is the most abundant iron species in magmas and in many slags. Its structural role in these liquids is poorly understood, largely because of the difficulty of studying melts at high temperatures

Transport Properties of Fe2SiO4 Melt at High Pressure From Classical Molecular Dynamics: Implications for the Lifetime of the Magma Ocean

The transport properties of silicate melts played important roles in various geodynamic processes during the evolution of the Earth. The dependence of transport properties on the temperature and

Spectroscopic and Structural Properties of Iron in Silicate Glasses

Among the infinite possibilities of glass compositions, soda-lime silicates represent of 90% of the glass production and are widely used for many industrial applications (e.g. automotive, solar

The Structure of Amorphous and Deeply Supercooled Liquid Alumina

Liquid Al2O3 has been supercooled more than 500 K below its melting point (Tm = 2327 K) using aerodynamic levitation and laser heating techniques. High energy synchrotron x-ray measurements were
