ABSTRACT:
A crystalline alumino-silicate having a powder X-ray diffraction diagram, a specific area, and a porous volume to nitrogen corresponding to offretite, and containing at least one metal selected from the groups I, II, VI, VII, VII, rare earth group, and/or at least an ammonium or quaternary ammonium group, presenting an aspect of the crystals as observed by electron microscopy in the form of hexagonal prisms with well defined edges of a length of 0.5 to 2.5 micrometers and a width of 0.1 to 1 micrometer.
