Combustion synthesis experiments in a fluidized bed have been conducted using nitrogen as the fluidizing gas for the formation of transition‐metal nitrides that are potential replacements for traditional hydrodenitrogenation and hydrodesulfurization catalysts. The microwave‐assisted ignition of reaction has been investigated for its potential to produce nitride overlayers on two different sizes of tantalum particle substrates. Various characterization techniques—X‐ray diffractometry, energy dispersive spectroscopy, scanning electron microscopy, and high‐resolution transmission electron microscopy—have been used to study the presence of nitride overlayers. The results indicate that microwave assistance can permit controlled formation of tantalum nitride (Ta 2 N) overlayers.
