Isakhiwo sesikrini sama-molecule

Isakhiwo sesihlungo sama-molecule sihlukaniswe amazinga amathathu:

Isakhiwo esiyinhloko: (i-silicon, i-aluminium tetrahedra)

Imithetho elandelayo iyalandelwa lapho i-silicon-oxygen tetrahedra ixhunyiwe:

(A) I-athomu ngayinye ye-oxygen ku-tetrahedron iyabiwa

(B) I-athomu eyodwa kuphela ye-oxygen engabiwa phakathi kwama-tetrahedra amabili aseduze

(C) Izinto ezimbili ze-aluminium azixhumene ngqo

Indandatho yesakhiwo sesibili

Isakhiwo sesibili- – indandatho ye-multivariate

Isakhiwo sesithathu- – - ikheji

Amayunithi esakhiwo sesibili axhunyaniswa ngokuqhubekayo ngebhuloho le-oxygen ukuze akhe i-polyhedr yesikhala esinezinhlangothi ezintathu, ebizwa ngokuthi imbobo noma umgodi, i-cage iyunithi eyinhloko yesakhiwo eyakha isihlungo sama-molecular zeolite; kufaka phakathi i-hexagonal column cage, i-cubic (v) cage, i-cage, i-B cage, i-eight-side zeolite cage, njll.

Amakheji ahlelwe kabusha ukuze akhe uhlaka lwe-zeolite
