5A molecular sieve is made by aluminosilicate, Because of its crystal structure whose diameter is 5A, it can totally adsorb all of substance whose diameter is less than 5A. 5A molecular sieve is widely usedfor drying and refining in petrochemical、natural gas、air separation、organic liquid and so on.
Chemical Formula：3/4Ca2O*1/4Na2O*Al2O3*2SiO2*9/2H2O
Si/Al ratio：SiO2/ Al2O3≈2
