摘要： A method of manufacturing a substrate having a plurality of micro-channels formed therein, the method comprising:
providing a suspension containing a substrate material in particulate form and a polymer in a first solvent; introducing the suspension into a mould or extruding the suspension;
contacting the suspension with a second solvent to remove at least some of the first solvent from the suspension and thereby form a green body having micro-channels from said substrate material and said polymer;
sintering the green body to form a sintered body; and removing at least a portion of a surface layer of the sintered body.
