Abstract

Official abstract text for this publication.

This method for producing porous sintered aluminum includes: mixing aluminum powder with a sintering aid powder containing titanium to obtain a raw aluminum mixed powder; mixing the raw aluminum mixed powder with a water-soluble resin binder, water, and a plasticizer containing at least one selected from polyhydric alcohols, ethers, and esters to obtain a viscous composition; drying the viscous composition in a state where air bubbles are mixed therein to obtain a formed object prior to sintering; and heating the formed object prior to sintering in a non-oxidizing atmosphere, wherein when a temperature at which the raw aluminum mixed powder starts to melt is expressed as Tm (° C.), a temperature T (° C.) of the heating fulfills Tm−10 (° C.)≦T≦685 (° C.).

First claim

Opening claim text (preview).

The invention claimed is: 1. Porous sintered aluminum comprising: metal skeletons having a three-dimensional network structure of perforated sintered metal, wherein pores exist between the metal skeletons, Al—Ti compound is dispersed in the perforated sintered metal, and the pores are formed at an amount of 20 or more pores per linear length of 1 cm, and thereby, an overall porosity is in a range of 70 to 99%, and pores exist in the metal skeleton of the perforated sintered metal.
