High-Pressure Multianvil Synthesis and Structure Refinement of Oxygen-Bearing Cubic Zirconium(IV) Nitride


  • We thank D. Trots for fruitful discussions concerning the Rietveld refinement method. The financial support of the Deutsche Forschungsgemeinschaft (Bonn, Germany) is gratefully acknowledged.


Macroscopic amounts of oxygen-bearing c-Zr3N4with a cubic Th3P4-type structure are synthesized for the first time (see figure) at high pressures and temperatures. Structure refinement based on X-ray diffraction data is performed. The Raman spectrum, morphology, and microhardness of the synthesized material is measured.
