摘要:
Method for producing molded metallic honeycomb structures of high physical strength and porosity, the method comprising forming a honeycomb structure by extruding through a die a kneaded mixture of a metal powder and a binder capable of forming a supporting bone structure for the metal powder upon application of heat, and, after drying, sintering the honeycomb structure.
摘要:
Non-permeable carbonized formed bodies consisting of carbonaceous material containing 5-50 wt % of graphite and the balance of glassy carbon formed by bake-carbonization of a thermosetting resin, and a method for producing such non-permeable carbonized formed bodies comprising mixing and kneading a thermosetting resin powder, thermosetting resin liquid and graphite powder, drying, hardening and bake-carbonizing the resultant body is disclosed.
摘要:
The invention is concerned with a porous molding obtained by extruding a mixture containing at least one material selected from porous inorganic materials and carbonizable organic materials and at least one binder therefor in the form of threads or strings, accumulating the thready or stringy extrudates to form a mass, and then drying and sintering the accumulated mass. When the at least one material is an organic material, the sintered mass is carbonized in a non-oxidative atmosphere and then activated as usual.
