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

Figure 4

XRD patterns of the tungsten nitride powders synthesized at nitrogen pressures of (a) 5 kPa, (b) 40 kPa. The diffraction peaks marked as “∗” and “•” correspond to the cubic W₂N and metal W, respectively.
