摘要： Porous articles consisting virtually entirely of beryllium metal are prepared by using iodine as a fugitive pore former. An admixture of beryllium powder and crystalline iodine is pressed into a compact and then heated in vacuum at a temperature of about 100° C. to sublime the iodine. The compact is thereafter sintered at a temperature of about 1000° C.

摘要： A porous metallic material having controlled patterns of interconnected voids specifically adapted for tissue ingrowth application. The material can be produced having interconnected voids of spherical or other desired shape, as well as oriented voids arranged in a pre-selected spatial pattern. The method of producing the porous structure involves the arrangement of solid expendable void former within a receiving cavity of a mold or form in a pattern corresponding to the size, shape and spatial pattern of the voids desired in the final matrix. Metallic powder formed of a biocompatible material is packed about the expendable void former and the composite material is subjected to high energy rate forming pressures to densify its structure. The expendable void former is then removed and the remaining matrix of metal is sintered to further strengthen the web structure that remains after removal of the void former.

摘要： A sintered metal, or ceramic filter having parallel, straight holes of uniform diameter and with smooth inner surfaces passing therethrough is formed by sintering a green compact about a large number of straight wires arranged parallel to one another. Upon application of heat at a sintering temperature above the melting point of the wire material and less than the melting point of the sintering powders, the wires are absorbed into the pores of the sintering powders and leave holes of the same shape and size as the original wires in the resulting sintered filter.

摘要： The production of foam material, e.g., a reticulated ceramic, metal or cermet material, is carried out by using commercially available conventional foam, such as reticulated polyurethane, having the desired pattern for the end product. This foam serves as a pattern for the mold and is embedded in mold material of plaster of paris or the like, which sets to form a solid structure in and around the plastic foam. This investment structure is then heated to volatilize and expel the plastic foam, leaving voids in the mold corresponding to the original configuration of the foam. Molten metal or other substance is then cast through the voids or openings in the mold and permitted to cool and set. The mold structure is then washed away, leaving a reticulated structure of integrally formed ligaments of metal, ceramic, cermet or other desired substance.

摘要： 1,141,814. Fuel cell electrodes. ROBERT BOSCH G.m.b.H. 6 July, 1966 [20 July, 1965], No. 30351/66. Heading H1B. Fuel cell electrodes comprising 2 bonded microporous layers of sintered nickel and silver particles are made by (a) forming a layer of finely divided nickel and finely divided silver carbonate, (b) forming another layer of finely divided nickel, finely divided silver carbonate and a removable pore-forming material in contact with it, (c) compressing the 2 layers, (d) sintering them and reducing the silver carbonate to metallic silver and (e) removing the pore forming material. The silver carbonate may be reduced with H 2 or by thermal decomposition in an inert gas stream. The first layer may be prepared from 40-80% silver carbonate and 60-20% nickel. The pore former may be a volatile material, e.g. ammonium carbonate, ammonium bicarbonate or ammonium carbamate, or a soluble material, e.g. Na 2 CO 3 , NaHCO 3 or MgCO 3 which is dissolved out after sintering. They may be of less than 100 mÁ grain size and 17-83% may be used. The layers 1-3 mm. thick, may be subjected to a pressure of 1-3 Kg/cm. 2 It may be sintered at 550-650‹ C. whilst being pressed flat. Reduced pressure may be used to remove volatile pore formers. The electrode may be used with air in a methanol cell at room temperature or in a hydrogen cell at room or elevated temperature. In a particular embodiment it (a) is retained by frame (c) in proximity to plate (e), the cavity between being sealed by ring (d). Current is collected by (f) and gas supplied at (g) and removed at (h). The electrode is immersed in 7N.KOH solution opposite a hydrogen electrode and air preheated to 70‹ C. is passed through at such a rate that no bubbles escape through the electrolyte. The air pressure may be 0À4-0À8 atmospheres gauge. In a modification of the invention the silver in layer (a) is replaced by nickel derived by heating basic nickel carbonate.
