PROBLEM TO BE SOLVED: To provide an improved crystalline zeolite utilized for efficiently separating argon from oxygen.;SOLUTION: An AgX type zeolite, which has a silver exchange degree of 20-70% and a constant ratio of Henry's law of Ar/O2 at 23°C of 1.05 or more, has an optimum combination of argon selectivity against oxygen at a lower cost than the relatively expensive silver exchange degree. The material has a purity of 97% or more and can be used for oxygen VSA(vacuum swing absorption)/PSA(pressure swing absorption) process for generating oxygen.;COPYRIGHT: (C)2003,JPO
