Kapangidwe ka sewero la maselo

Mapangidwe a molecular sieve amagawidwa m'magulu atatu:

Kapangidwe kake: (silicon, aluminium tetrahedra)

malamulo otsatirawa amawonedwa pamene tetrahedra ya silicon-oksijeni ilumikizidwa:

(A) Atomu iliyonse ya okosijeni mu tetrahedron imagawidwa

(B) Ma atomu amodzi okha a okosijeni amatha kugawidwa pakati pa ma tetrahedra awiri oyandikana nawo

(C) Zida ziwiri za aluminiyamu sizigwirizana mwachindunji

Sekondale kapangidwe-mphete

Kapangidwe kachiwiri - - -multivariate mphete

Kapangidwe kapamwamba--- khola

Magawo achiwiri amapangidwe amalumikizana wina ndi mnzake kudzera mu mlatho wa okosijeni kuti apange polyhedr yokhala ndi mbali zitatu, yotchedwa dzenje kapena dzenje, khola ndi gawo lalikulu lazinthu zomwe zimapanga zeolite molecular sieve; kuphatikiza khola la hexagonal, cubic (v) khola, khola, B khola, khola lazeolite lambali eyiti, ndi zina zambiri.

Makola amakonzedwanso kuti apange mafupa a zeolite
