Overview
ABSTRACT
This article compiles the numerical values of enthalpy variations, between 25°C and various temperatures, for pure substances, elements, and compounds. It also includes the temperatures and enthalpy variations associated with phase transformations of some of these pure substances. Enthalpy of formation values for compounds at different temperatures are also reported. Secondly, a technique for evaluating the enthalpy of dissolution of elements in pure or low-alloyed liquid iron is presented. Finally, the document also presents data relative to various industrial materials such as steelmaking slags, fuels, coke, and pig iron.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
This article provides engineers with all the thermochemical data needed to prepare heat balances in pyrometallurgy, particularly in the steel industry.
Commercial software programs largely rely on the data presented in this article. These programs enable enthalpy calculations in a wide range of situations. However, handling complex cases requires specific training.
To meet the specific needs of the steel industry, § 1 and § 2 cover systems consisting either of pure chemical elements or of stoichiometric compounds that are heated from 25 °C to a temperature .
