Ulwakhiwo lwesikrini se-molecular

Ulwakhiwo lwesihluzo se-molecular lwahlulwe lwangamanqanaba amathathu:

Ulwakhiwo oluphambili: (i-silicon, i-aluminium tetrahedra)

Le mithetho ilandelayo iyalandelwa xa i-silicon-oxygen tetrahedra iqhagamshelwe:

(A) I-athomu nganye yeoksijini kwi-tetrahedron yabelwana ngayo

(B) I-athomu enye kuphela yeoksijini enokwabelwana ngayo phakathi kwee-tetrahedra ezimbini ezikufutshane

(C) Izinto ezimbini ze-aluminium azidibananga ngokuthe ngqo

Isangqa sesibini sesakhiwo

Isangqa sesibini- – - i-multivariate ring

Isakhiwo sesithathu- – - ikheyiji

Iiyunithi zesakhiwo sesibini ziqhagamshelwe ngakumbi ngebhulorho yeoksijini ukuze zenze i-polyhedr yesithuba esinemilinganiselo emithathu, ebizwa ngokuba yi-hole okanye i-hole cavity, i-cage yiyunithi yesakhiwo ephambili eyenza isihluzo se-molecular zeolite; kubandakanya i-hexagonal column cage, i-cubic (v) cage, i-cage, i-B cage, i-eight-side zeolite cage, njl.njl.

Iikheji zicwangciswa ngakumbi ukuze zenze iskeleton se-zeolite
