  • Zeolite encapsulating material
    Patent number: 4466812
    Abstract: A zeolite encapsulating material composed of an A-type zeolite expressed by a typical unit cell (CsxMII.sub.y Naz)(AlO.sub.2.SiO.sub.2).sub.12 .multidot.(NaAlO.sub.2).delta..multidot..omega.H.sub.2 O wherein MII represents a divalent metal; O.ltoreq..delta..ltoreq.1; and .omega. represents a positive number. Further, in the above stated unit cell, x, y and z which respectively represent the numbers of Cs, M and Na within the unit cell are in a relation:x+2y+z=123.ltoreq.x<100<y.ltoreq.4.5.
    Type: Grant
    Filed: August 2, 1982
    Date of Patent: August 21, 1984
    Assignee: Toyo Soda Manufacturing Co., Ltd.

  • Zeolite encapsulating material
    Patent number: 4461631
    Abstract: A zeolite occluding material composed of an A-type zeolite expressed by a generic formula (Kx My Naz)(AlO.sub.2.SiO.sub.2).sub.12.(NaAlO.sub.2).delta...omega.H.sub.2 O wherein M represents a bivalent metal; O.ltoreq..delta..ltoreq.1; and .omega. represents a positive number. Further, in the above stated unit cell, x, y and z which respectively represent the numbers of K, M and Na within the unit crystal lattice (or unit crystal cell) are in a relation:x+2y+z=123.ltoreq.x<101<y.ltoreq.4.5.
