This species has low Si content, about 27 per unit cell, and high water, 23 to 25 H 2 O per cell. Alkali-dominant heulandite (heulandite-Na and heulandite-K), which has the highest Si, limited …

Unit cell dimensions are given for two different contracted phases, phase 1 and phase B of a dehydrated heulandite from Cape Blomidon, Nova Scotia. The phases appear at temperatures …

Explore the zeolite HEU crystalline lattice structure of K0.215Na0.63Ba0.03Sr0.025Ca1.785Mg0.005Al4.685Si13.35O36 [H2O]13.01 with lattice …

As of 2021 there are now IMA–CNMNC approved mineral symbols (abbreviations) for each mineral species, useful for tables and diagrams. Please only use the official IMA–CNMNC …

1998年5月1日 · Heulandite-clinoptilolite zeolites can be synthesized over the complete range of Si/Al ratio (2.5 to 6) found for the natural minerals. The unit cell parameters, framework …

2001年1月1日 · the unit-cell parameters for heulandite are distinct from those for clinoptilolite, but the sensitivity of the unit-cell parameters to ch anges in water content (e.g. Bish 1984) makes...

Unit cell dimensions are given for two different contracted phases, phase I and phase B of a dehydrated heulandite from Cape Blomidon, Nova Scotia. The phases appear at temperatures …

The crystal structure of heulandite is characterized by large intersect- ing channels composed of l2-, 10-, and S-member rings open across the mirrors and tied together by layers of 6-, 5-, 4 …

In this paper a heulandite is described in which cavities or channels normally unoccupied by water contain nearly six molecules of water, giving a unit cell content of nearly 30 instead of the …
