Ubume besikrini semolekyuli

Isakhiwo se-molecular sieve sahlulwe ngokwamanqanaba amathathu:

Isakhiwo sokuqala: (isilicon, i-aluminium tetrahedra)

le mithetho ilandelayo iyaqwalaselwa xa i-silicon-oksijini tetrahedra idityanisiwe:

(A) Iathom nganye yeoksijini kwi-tetrahedron yabelwana ngayo

(B) Inye kuphela iathom yeoksijini enokwabelwana ngayo phakathi kweetetrahedra ezimbini ezimeleneyo

(C) Izinto ezimbini ze-aluminium azixhunyiwe ngokuthe ngqo

Isakhiwo sesibini-ringi

Ulwakhiwo lwesibini- – -multivariate ring

Isakhiwo senqanaba eliphezulu- – - ikheji

Iiyunithi zesakhiwo sesibini zidibaniswe kunye nomnye ngebhulorho ye-oksijini ukwenza i-polyhedr yesithuba se-three-dimensional, ebizwa ngokuba ngumngxuma okanye umngxuma womngxuma, i-cage iyona yunithi yesakhiwo ephambili eyenza i-zeolite molecular sieve; kuquka i-hexagonal column cage, i-cubic (v) i-cage, i-cage, i-B cage, i-cage ye-zeolite enecala elisibhozo, njl.

Iikheji ziphinda zicwangciswe ukuze zenze i-zeolite skeleton
