The Melting Point-Composition Diagram of the Zirconium-Oxygen System

Daniel Cubicciotti

The solidus curve of the zirconium-zirconium dioxide system has been investigated by observing the melting points of wires of the oxidized metal. The results show that near the melting points oxygen dissolves to the extent of 55 atom per cent. in solid zirconium metal, while zirconium dissolves in the solid dioxide to form a 15 mole per cent. solution. No evidence was found for compounds other than the dioxide. © 1951, American Chemical Society. All rights reserved.
