In the 3rd blog post of this series related to the Blast Furnace Diagram, we at first consider the effect of including the metallic phases as solution phases instead of considering them as pure compounds, like we already did for the oxides. Then, we show how the total pressure will affect the diagram, in special …

In the second blog post of this series related to the Blast Furnace Diagram, we explore some variations of the diagram constructed in the first blog post, while sticking to carbon as the only reducing agent in the system. This blog post was written in collaboration with Klaus Hack. The first diagram that we will …

The so-called blast-furnace diagram describes which phases are stable in the different regions of the blast furnace, depending on the conditions of temperature and of the atmosphere inside the furnace[1]. It is basically a phase diagram, where the volume fraction of CO is represented on the X-axis and the temperature is represented on the Y-axis, …

The loss of copper in the converting process through its incorporation to the converter slag represents a major problem in the copper metallurgy. There are two important mechanisms for this phenomenon: the physicochemical and the mechanical one. The mechanical mechanism, i.e. the mechanical entrapment of matte or of metallic copper inside the slag, is by …

Mats Hillert has shown [*] that what is called a Phase Diagram is derivable from a projection in a so-called Property Diagram. The (molar) Gibbs Energy as the property is plotted along the z-axis as a function of two other variables x and y. For binary systems, for example, T equals y and the mole …

FactSage contains many modules. The major ones for daily work are Equilib and Phase Diagram. Phase Diagram permits the calculation of phase diagram sections for systems with any number of components. Components can be elements, compounds or even arbitrary compositions. For a phase diagram calculation, first the components of interest have to be defined. Then, the possible …
