Defects in these materials were characterized by using high-resolution electron microscopy. The defects were identified as being linear, planar and 3-dimensional. They could result in pore blockage of the mordenite channel structure and be detrimental to catalytic phenomena. The planar defects were the most severe ones to affect the structural properties of mordenite. This was because of their density and scale.
