Modeling of the Thermochemical Properties of Multicomponent Oxide Melts
-
Reinhard Conradt
Abstract
Two approaches are presented by which the thermochemical properties of multicomponent oxide melts can be modeled and estimated at an accuracy well sufficient for the treatment of industrial processes. Both approaches exploit information on the number, chemical composition, and constitutional relations of compounds in the crystalline reference system of a given melt. Both models use data on individual components and compounds only and do not require any additional information on thermodynamic excess data.
Abstract
Es werden zwei Ansätze vorgestellt, mit deren Hilfe thermochemische Eigenschaften vielkomponentiger Oxidschmelzen modelliert und mit einer Genauigkeit abgeschätzt werden können, wie sie für eine Behandlung industrieller Prozesse erforderlich ist. Beide Ansätze nutzen die Kenntnis der Anzahl, der chemischen Zusammensetzung und der Phasenbeziehungen der Verbindungen im kristallinen Bezugssystem der jeweiligen Schmelze. Beide Modelle benötigen nur die Daten der Komponenten und Verbindungen; die zusätzliche Kenntnis thermodynamischer Exzess-Daten ist nicht erforderlich.
