Ụdị AMolecular sieve

Isi ihe dị na sieve ụdị A bụ silicon aluminate. Isi oghere kristal bụ nhazi octaring. Oghere nke oghere kristal bụ 4Å(1Å=10-10m), nke a maara dị ka sieve ụdị 4A (a makwaara dị ka ụdị A); Gbanwee Ca2 + maka Na + na sieve ụdị molekul 4A, na-emepụta oghere nke 5A, ya bụ sieve ụdị 5A (a makwaara dị ka calcium A); K+ maka sieve ụdị molekul 4A, na-emepụta oghere nke 3A, ya bụ sieve ụdị 3A (a makwaara dị ka potassium A).

Mkpọchi molekụla ụdị X

Isi ihe dị na X molekul sieve bụ silicon aluminate, isi oghere kristal bụ nhazi mgbanaka ihe iri na abụọ. Ụdị kristal dị iche iche na-emepụta kristal sieve molekul nwere oghere nke 9-10 A, nke a na-akpọ 13X (a makwaara dị ka sodium X ụdị) molekul sieve; Ca2 + gbanwere maka Na + na sieve molekul 13X, na-emepụta kristal sieve molekul nwere oghere nke 8-9 A, nke a na-akpọ sieve molekul 10X (a makwaara dị ka calcium X).
