Abstract

The solid transformation of tungsten trioxide to a cubic tungsten carbide via nitride has been studied. Product carbide particles possessed specific surface area ofca. 90 m2g*-1 and average diameter ofca. 4 nm. Transmission electron microscope (TEM) exhibited that these particles formed porous aggregates with a spotty electron diffraction pattern. This provides an evidence that the topotactic solid transformation has been involved.
