Effect of Nitrogen Pressure on the Structure of Cr-N, Ta-N, Mo-N, and W-N Nanocrystals Synthesized by Arc Discharge

Figure 1

XRD patterns of the tantalum nitride powders synthesized at nitrogen pressures of (a) 10 kPa, (b) 40 kPa. The diffraction peaks marked as “∗” and “•” correspond to the cubic TaN and hexagonal Ta₂N, respectively.
