Abstract: Disclosed are a high silica zeolite having a novel crystal structure, a zeolite membrane and methods for producing them. The zeolite is represented by the chemical composition:[(Si36-xTy·O72)·Mz] (wherein M represents a cation of an alkali metal such as Li, Na, K and Rb; T represents Al, Ga, Fe and Ce as skeleton substituting elements; and x satisfies 0 ≤ x ≤ 3.0, y satisfies 0 ≤ y ≤ 1.0, and z satisfies 0 ≤ z ≤ 3.0), and has a micropore composed of a covalent bond of Si-O. The zeolite has a specific diffraction peak at 2θ in the powder x-ray diffraction pattern.

Abstract: To provide a composite that can find application to various uses in a wide spectrum of fields, for example, sealing members, such as a joint sheet, a gasket and a packing, for use in junction portions, etc. of pipings of power plant and chemical plant, radiation sheets, electromagnetic wave shielding members, soundproof sheets, etc., and provide a process for producing the composite; a gasket or packing based on the composite and a clay dispersion liquid used for the composite. There is provided a composite composed mainly of graphite and clay and having the structure of graphite laminated with and/or impregnated with clay. The composite is produced by subjecting an exfoliated graphite sheet or film or a molding therefrom to coating with and/or immersion in a clay dispersion liquid with clay particles dispersed therein, or by laminating together of an exfoliated graphite sheet and/or film and a sheet and/or film composed mainly of clay. Further, a gasket or packing is produced by molding the composite.
