Abstract
PURPOSE: To make possible the inexpensive production of a tubular sintered filter of superior performances under high productivity by mixing specific amounts of cellulose and lubricant into metal powder, and extrusion-molding this mixture then sintering the molding.
CONSTITUTION: 1W7wt% cellulose such as methyl cellulose as a binder and 0.2W 2.0wt% stearate such as zinc stearate and calcium stearate as a lubricant are mixed in the powder of stainless steel or the like. This mixture is extruded and molded to a tubular shape, after which the molding is dewaxed for 30min at 500°C and is further sintered for 1hr at 1,200°C in an inert gas. If a heat-resistant medium such as alumina or sand is beforehand packed in the inside hole of the thus molded pipe at the time of sintering, a bend-free pipe is obtained. The tubular sintered filter of superior filter performances may be produced inexpensively under high productivity.
