Tsarin allon kwayoyin halitta

Tsarin sieve kwayoyin halitta ya kasu kashi uku:

Tsarin farko: (silicon, tetrahedra aluminum)

Ana kiyaye dokoki masu zuwa lokacin da aka haɗa tetrahedra silicon-oxygen:

(A) Ana raba kowane zarra na oxygen a cikin tetrahedron

(B) Oxygen atom guda ɗaya ne kawai za a iya raba tsakanin tetrahedra guda biyu da ke kusa

(C) Abubuwan aluminum guda biyu ba su da alaƙa kai tsaye

Tsarin na biyu-zobe

Tsarin na biyu - - - zobe mai yawa

Tsarin manyan makarantu - - - keji

Ƙungiyoyin tsarin na biyu suna ƙara haɗawa da juna ta hanyar gadar oxygen don samar da sararin samaniya mai girma uku polyhedr, wanda ake kira rami ko rami, keji shine babban tsarin tsarin da ke samar da simintin kwayoyin zeolite; ciki har da kejin shafi hexagonal, cubic (v) keji, keji, kejin B, kejin zeolite mai gefe takwas, da sauransu.

An ƙara shirya cages don samar da kwarangwal na zeolite
