Development of thermodynamic database of metallurgical melt;

Proceeding from the concepts and definitions of the activities of components in metallurgical melts and their standard states, the discrepancies about applying the mass fraction and mass percent concentration to metallurgy were analyzed and discussed.

Based on morphology, it is presented that morphotype conversion of foams in metallurgical melts would occur during foam evolution, which has been proved by experimental results.

The present paper describes the functions, structure as well as the features of " Computerized thermophysical data bases for metallurgical melts".

The leaching residue of low-grade lithopone is treated with pollution-free normal temperature alkaline smelting.
