Abstract
The present invention relates to a method of manufacturing a metal-impregnated body by immersing a porous ceramic or ceramic powder in a solution containing a chemical compound having an OH radical selected from the group consisting of water and aqueous solutions of methanol, ethanol, butanol, acetone, acetic acid and ammonium hydroxide; drying and molding it into a porous body; and then impregnating said porous body with a molten metal.
Claims8
A method of manufacturing a nitride ceramic impregnated with a molten metal comprising the steps of treating a porous shaped or powdered nitride ceramic with a liquid or solution containing a compound having an OH radical, said solution or liquid selected from the group consisting of water or an aqueous solution of methanol, ethanol, butanol, acetone, acetic acid, or ammonium hydroxide, drying said ceramic to expose an active ceramic surface, molding said ceramic into a solid body before it is impregnated with a molten metal and impregnating said ceramic with a molten metal which remains in substantially uncombined form after impregnation.
