Bulk chemical compositions of N, C, H contents of amorphous Ti₃N₄ materials prepared in this study and used as precursors for high-P,T annealing experiments. The compounds were produced by precipitation from THF solution following ammonolysis of dialkylamide metal precursors followed by treating at 350–400 °C in flowing NH₃.
