the porosity and shrinkage was designed. As a pore former, a potato starch was used. For the control of shrinkage, the oxidatio nof Al metal particles was used. For the sintering of the above powder mixtures, a partial sintering technique was used at 1300oCfor 10 min in air. Upon adding the additives, high open porosity above 53% and a low shrinkage level were obtained. As a result ,cracking and warping of the sintered body were deterred. This outcome most likely resulted from the compensation of sinteringshrinkage due to the volume expansion caused by oxidation of the Al metal particles during heat-treatment.
