Cancrinite crystal , scanning electron

The relative products have been referred to as Li,Cs-C, CAN Li,Tl-C, CAN and Li,Tl,Cs-C, CAN, respectively. Figures 1 and 2 report in particular two scanning electron micrographs of the second ar.d the third samples, in which the exagonal cross section of the prismatic cancrinite crystals is well visibile.
