Standard Gibbs Free Energy of Formation of MnO-saturated MnO Cr2O3 Solid Solution at 1873K.

Calculation of MnO Activity in Aluminate Slags at Various Temperatures

In this research, the activity of MnO, produced during steel making in aluminate-rich slags, was investigated. According to thermodynamic equations and mathematical calculation, a series of relations was obtained for evaluation of oxide activity using Masson’s theory. The obtained relations were solved according to Levenberg- Marquardt method and using Matlab software. The results were correlat...

The Gibbs free energy of formation of a glassy alloy

A simple expression for the Gibbs free energy of formation of a pure component or a eutectic alloy glass, relative to the stable crystalline phase (or phases) at the same temperature is deduced by use of thermodynamic arguments. The expression obtained is supposed to apply to both monocomponent and multicomponent liquid alloys that might become glasses from the supercooled liquid state, irrespe...

Antiferromagnetic spin correlations in MnO nanoparticles

We have investigated nearly monodispersive MnO nanoparticles of 10 nm diameter by polarised neutron diffraction with XYZ-polarisation analysis. We found no long-range ordering down to 3.5K. A broad magnetic peak appeared close to Q1⁄4 (1/2,1/2,1/2) signifying short-range antiferromagnetic correlations. The correlation length was found to be about 2.4 nm at T1⁄43.5 K. The correlation length decr...
