Interstitially stabilized phases in the zirconium-nickel system
Abstract
Addition of nonmetal interstitial atoms to Zr-Ni compounds has resulted in several new phases. A single-crystal x-ray study was carried out for Zr3NiO. Zr4Ni2O is a high- temperature phase, forming in samples annealed at 1250 C. Huekel band calculations led to prediction and confirmation of additional phases in more electron rich systems. Other phases studied by XRD are Zr6Ni4Ti2O0.6, Nb6Ni6O, and Nb6Ni4Ta2O2. Phases identified by powder diffraction are Nb4Ni2O, Zr4Cu2O, and Zr6Co4Ti2O. New Zr kappa phases in space group P6s3/mmc were found: Zr9Mo4SOx and Zr9W4(S,Ni)O3. A new structure type was discovered with Zr6Ni6TiSiO1.8. In all these interstitially stabilized phases, O is coordinated in Zr octahedral; there are no Ni-O interactions.
