13X molecular sieve is made by aluminosilicate. It is formed X style crystal structure(X-Na molecular sieve) whose diameter is 10A, so it can totally adsorb all of substance whose diameter is less than 10A. It is usually used as excellent desiccant in fine chemical and air separation.
Chemical Formula：Na2O*Al2O3*（2.8±0.2）SiO2*（6-7）H2O
Si/Al ratio：SiO2/ Al2O3≈2.6-3.0
