Abstract
Shaped metal-containing ceramic articles are formed from a plastic material containing a hydrosilicate and powdered metal, alloy, metal oxide, or ore, the article being heated to remove combined water, treated in a reducing atmosphere while still porous to reduce any metallic oxide present or formed by the action of watervapour during the earlier heating, and finally heated to effect sintering. The article is shaped from a mixture of a hydrosilicate, such as clay, kaolin, talc, bentonite, halloysite, or allophane, and a metal, metal oxide, or metal ore powder, e.g., iron, copper, nickel, molybdenum, or tungsten, to which may be added other ceramic raw materials, fluxes such as felspar, boric acid or borates, and non-plastic materials such as silica, grog, or silicon carbide. The article is dried, heated, to expel combined water, to a temperature of about 700 DEG C., and then heated in an atmosphere of hydrogen, carbon monoxide, or a hydrocarbon, or in the presence of sufficient carbon to produce carbon monoxide. After all the oxide has been reduced the temperature is raised to sinter the powders together. Specification 270,300, [Class 70], is referred to.ALSO:Shaped metal-containing ceramic articles are formed from a plastic material containing a hydrosilicate and powdered metal, alloy, metal oxide, or ore, the article being heated to remove combined water, treated in a reducing atmosphere while still porous to reduce any metallic oxide present or formed by the action of water-vapour during the earlier heating, and finally heated to effect sintering.
