  • Tabung molekular (ogé katelah zekitar sintétik) mangrupikeun kristal mikropis silang. It is a basic skeleton structure composed of silicon aluminate, with metal cations (such as Na +, K +, Ca2 +, etc.) to balance the excess negative charge in the crystal.

Komponén utama ngetik tabung molekular nyaéta silicon alumasi. The main crystal hole is octaring structure.The aperture of the main crystal aperture is 4Å(1Å=10-10m), known as type 4A (also known as type A) molecular sieve; Exchange the Ca2 + for the Na + in the 4A molecular sieve, forming an aperture of 5A, namely a 5A type (aka calcium A) molecular sieve;K+ for a 4A molecular sieve, forming an aperture of 3A, namely a 3A (aka potassium A) molecular sieve.

The main component of X molecular sieve is silicon aluminate, the main crystal hole is twelve element ring structure.Different crystal structure form a molecular sieve crystal with a aperture of 9-10 A, called 13X (also known as sodium X type) molecular sieve;Ca2 + exchanged for Na + in a 13X molecular sieve, forming a molecular sieve crystal with a aperture of 8-9 A, called a 10x (ogé katelah kalsium X) tabung molekular.
