“…The common methods of synthesizing pure titanium nitride (rather than low level N-doped titania) include physical vapour deposition (PVD), 36 reactive sputtering, 37 cathodic arc deposition, 38,39 plasma-gas reaction, 40 and CVD. 41 Methods such as PVD and CVD are less effective in synthesizing nano-sized products (products tend to be in the m size range). 34,41 TiN powders prepared by plasma-gas phase reaction have a smaller particle size (ca.…”
