3a Molecular Sieve Desiccant For General Gas Dehydration
Product Description
3A molecular sieve has a pore size of 3A or 3 angstrom. Any molecule larger than 3A will not be able to be adsorbed. Mole Sieve is an alkali metal alumino-silicate, the potassium form of the type A crystal structure. 3 Angstrom is created when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions.
Chemical Formula:
2/3K2O*1/3Na2O*Al2O3*2SiO2*9/2H2O
