Patent

CA 2421626

A high-surface-area tungsten carbide material is provided. The material has a unique structure as defined by its x-ray diffraction pattern and consists of extremely small crystallites on the order of about 15 to about 30 angstroms in size. The hihg-surface-area of at least about 6 m2/g is desirable for catalyst applications.

L'invention concerne un matériau à base de carbure de tungstène de surface active étendue. Le matériau présente une structure unique définie par le diagramme de diffraction des rayons X et consiste en des cristallites extrêmement petites de l'ordre d'environ 15 à environ 30 angströms. Selon l'invention, la surface active étendue d'au moins environ 6 m?2¿/g est souhaitable dans des applications catalytiques.
