Development of a Thermodynamic Database for Copper Smelting and Converting

The high-temperature part of the diagram contains p-T domains of thermodynamic stability of rhombohedral b-B 106 , orthorhombic c-B 28 , pseudo-cubic (tetragonal) t’-B 52 , and

where is the partial pressure of oxygen in the standard state, i.e. the partial pressure of oxygen in equilibrium with Cu 2 O. RESULTS AND DISCUSSION.. The equilibrium

Oxygen diffusion (related to the oxide ionic conductivity) and/or oxygen surface exchange, characterized by the D O and k coefficients could be the limiting parameters

As mentioned previously, as regards the Gd-doped samples, the physical pa- rameters that characterise the model are obtained from electrical conductiv- ity data. Concerning

Their conclusions (clusters (10/4), (13/5) and (16/7) of blende ZnS type), which would be validated by the success of the same model applied to spinels, would be in better agreement

Fig.5 shows the reflected power as a function of the detector angle measured from the specular position for unpolarized radiation.. The cause of this wide tail

Nous montrons que les équations du système discret endommageable sont équivalentes à une formulation en différences finies centrée d’un problème d’endommagement continu
