Effect of oxygen and sulphur content in melts on performance of sodium reduced tantalum powders

摘要

The paper presents a study into joint and several effect of oxygen and sulphur content in melts on the engineering performance of the tantalum powders produced by sodium thermal reduction from melts based on potassium heptafluotantalate,tantalum oxycompounds and sodium chloride with and without addition sulfur-containing compound.
