Results and discussion

Any other information on results incl. tables

The diffractogram indicates the material is crystalline in nature, with major peaks at-

36.638 °2θ

42.569 °2θ

61.787 °2θ

 

The diffractogram is a good match with Powder Diffraction File*(PDF) 03-065-0565 N Ti Titanium Nitride.
