Partially dealuminated heulandite produced by acidic REECl3 solution: A chemical and single-crystal X-ray study
Partially dealuminated heulandite acidic REECl3solution:X-ray single-crysta
2012/3/31
Single crystals (0.1(R)C0.5 mm) of natural heulandite from Nasik (India) were treated in M NaCl
solution at 423 K for 12 weeks, yielding almost fully Na-exchanged heulandite (composition:
Ca K [Al ...

X-ray Study the Interlayer Region Barium— Vermiculite
2012/2/13
An X-ray diffraction analysis of a barium-vermiculite shows it to have a triclinic unit cell with the following dimensions a = 5.33, b = 9.26, c = 12.47 侌, 兛 = 100.75亱 兝 = 93.5亱 and 兞 = 90亱. The propo...
Lysine and vermiculite form a stable, ordered, interlamellar complex which has a well defined superlattice structure with respect to the ab-plane of vermiculite. The lysine molecules lie at a low angl...
