We report on the thermal and electrical conductivities of two liquid silicon-oxygen-iron mixtures (Fe0.82Si0.10O0.08 and Fe0.79Si0.08O0.13), representative of the composition of the Earth’s outer core at the relevant pressure-temperature conditions, obtained from density functional theory calculations with the Kubo-Greenwood formulation. We find thermal conductivities k = 100(160) W m −1 K −1 , and electrical conductivities σ = 1.1(1.3) × 10 6 � −1 m −1 at the top (bottom) of the outer core… 

Electrical and thermal conductivity of Earth’s core and its thermal evolution—A review

The Earth’s core is composed of iron, nickel, and a small amount of light elements (e.g., Si, S, O, C, N, H and P). The thermal conductivities of these components dominate the adiabatic heat flow in

Saturation of electrical resistivity of solid iron at Earth’s core conditions

The present results support the saturation effect idea, showing that at low temperature the resistivity increases linearly with temperature, and saturates at high temperature.

Thermal conductivity of Fe-Si alloys and thermal stratification in Earth’s core

A near temperature independence of the resistivity in iron-silicon alloys at Earth core’s pressure and thus a high thermal conductivity is found, indicating that if silicon is the sole major light element in Earth's core it could depress thermal convection and promote a thermally stratified layer at the topmost outer core.

Experimental determination of the electrical resistivity of iron at Earth's core conditions.

The low electrical resistivity of iron indicates the high thermal conductivity of Earth's core, suggesting rapid core cooling and a young inner core less than 0.7 billion years old.

Chemical Composition of the Outer Core

The Earth’s core is thought to composed of Fe⊖Ni alloys with large amounts of light elements. The composition of the present Earth’s outer core reflects various processes, such as core formation,



Thermal and electrical conductivity of iron at Earth’s core conditions

New estimates indicate that the adiabatic heat flux is 15 to 16 terawatts at the CMB, higher than present estimates of CMB heat flux based on mantle convection; the top of the coremust be thermally stratified and any convection in the upper core must be driven by chemical convection against the adverse thermal buoyancy or lateral variations in CMBHeat flow.

Structure and dynamics of liquid iron under Earth’s core conditions

First-principles molecular-dynamics simulations based on density-functional theory and the projector augmented wave (PAW) technique have been used to study the structural and dynamical properties of

Temperature of the inner-core boundary of the Earth: Melting of iron at high pressure from first-principles coexistence simulations

The Earth's core consists of a solid ball with a radius of 1221 Km, surrounded by a liquid shell which extends up to 3480 km from the center of the planet, roughly half way toward the surface (the

Electrical resistivity and thermal conductivity of liquid Fe alloys at high P and T, and heat flux in Earth’s core

First-principles electronic structure computations to determine the thermal conductivity and electrical resistivity for Fe, Fe–Si, and Fe–O liquid alloys agree very well with existing shock compression measurements and shows strong dependence on light element concentration and type.

Thermal conductivity of hcp iron at high pressure and temperature

Results of steady-state heat transfer experiments on iron in laser-heated diamond anvil cell, combined with numerical simulation using finite-element method are reported. Thermal boundary conditions,

using first-principles molecular dynamics. Our results are consistent with measurements at low pressures, and indicate that electronic transport coefficients σ and κ increase under compression; with
