A Pressure Dependence Of Thermal Conductivity λ Of Ferropericlase At Download Scientific

A Pressure Dependence Of Thermal Conductivity λ Of Ferropericlase At Download Scientific The room temperature thermal conductivity (λ) of ferropericlase (mg 1–x fe x)o with variable compositions (x fe = 0.03, 0.05, 0.10, 0.20, 0.30 and 0.50) at 1 bar can be derived from the pressure dependence fitting function (table s1 in supporting information s1). (a) pressure dependence of thermal conductivity λ of ferropericlase at 295 k: fitting results of measurement values are shown in dashed lines; fitting results of calculated single crystal values.

A Pressure Dependence Of Thermal Conductivity λ Of Ferropericlase At Download Scientific Download scientific diagram | (a) pressure dependence of thermal conductivity λ of ferropericlase at 295 k: fitting results of measurement values are shown in dashed lines; fitting results of. We have simultaneously measured thermal conductivity (λ) and thermal diffusivity (κ) for polycrystalline ferropericlase with different fe contents (fp 3, fp 5, fp 10, fp 20, fp 30 and fp 50) up to 23 gpa and 1100 k by a pulse heating method. experiment results reveals that even small amounts of fe in ferropericlase can strongly reduce the. The effects of the spin transition on the electronic structure, thermal expansivity and lattice thermal conductivity of ferropericlase are studied by first principles calculations at high pressures. Thermal conductivity of (mg, fe)o is reduced by iron substitution and spin crossover. •. thermal conductivity of lower mantle at cmb is determined to be 11.1 ± 1.7 w m k. (mg, fe)o ferropericlase (fp) is one of the important minerals comprising earth's lower mantle, and its thermal conductivity could be strongly influenced by the iron.
