- Abstract
-
The solid transformation of tungsten trioxide to a cubic tungsten carbide via nilride has been
studied. Product carbide particles possessed specific surface area of ca. 90 mag -I and average diameter of ca.
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.
