Uhlobo lwe-Amolecular sieve

Ingxenye eyinhloko yesihluzo sama-molecule sohlobo A yi-silicon aluminate. Umgodi oyinhloko wekristalu uyisakhiwo se-octaring. Umgodi womgodi oyinhloko wekristalu ungu-4Å(1Å=10-10m), owaziwa ngokuthi isihluzo sama-molecule sohlobo 4A (owaziwa nangokuthi uhlobo A); Shintsha i-Ca2 + ibe yi-Na + esihluzweni sama-molecule se-4A, kwakha umgodi ongu-5A, okungukuthi isihluzo sama-molecule sohlobo 5A (owaziwa nangokuthi i-calcium A); i-K+ ibe isihluzo sama-molecule se-4A, kwakha umgodi ongu-3A, okungukuthi isihluzo sama-molecule se-3A (owaziwa nangokuthi i-potassium A).

Uhlobo X isihlungi sama-molecule

Ingxenye eyinhloko yesihlungi sama-molecule e-X yi-silicon aluminate, umgodi oyinhloko wekristalu uyisakhiwo sendandatho yezinto eziyishumi nambili. Isakhiwo sekristalu esihlukile sakha ikristalu yesihlungi sama-molecule enombobo ongu-9-10 A, obizwa ngokuthi isihlungi sama-molecule esingu-13X (owaziwa nangokuthi uhlobo lwe-sodium X); i-Ca2 + ishintshaniswa ne-Na + kusihlungi sama-molecule esingu-13X, yakha ikristalu yesihlungi sama-molecule enombobo ongu-8-9 A, obizwa ngokuthi isihlungi sama-molecule esingu-10X (owaziwa nangokuthi i-calcium X).
