TL;DR: In this article, the effects of bath agitation on the microstructure, morphologies of the phases, and formation of various layers across the freeze-lining deposit were studied at steady-state conditions.

TL;DR: In this article, a systematic investigation has been carried out to determine the effects of temperature, reduction/oxidation time, and partial pressure of hydrogen on the extent of the oxygen and sulfur removal during basic nickel carbonate (BNC) processing under laboratory conditions.

TL;DR: In this article, a technique has been developed that allows the controlled reduction of small oxide particles in high-velocity gas streams, thus preserving the growth structures present at temperature, and a novel way of preparing delicate samples for examination in the scanning electron microscope and giving examples of the improved quality of metallographic information attainable using these techniques.

TL;DR: In this paper, the phase equilibria and liquidus temperatures in the ZnO-FeO-Al2O3-CaO-SiO2 system in equilibrium with metallic iron have been determined experimentally in the temperature range 1383 −K to 1573 −K (1150 −C to 1300 −C).

TL;DR: In this article, the liquidus isotherms and invariant lines in the FeO-SiO2-PbO slag system in equilibrium with air and with metallic lead have been constructed.
