Foam filters of MgO-PSZ fired at low temperature

Li Wenxia, Hu Yaohe, Guo shiju( University of Science and Technology Beijing, Beijing 100083)  
Preparing and researching of cerarnic foam filters with a new type of MgO-PSZ have been conducted. It was foundthat the Properties of the filtere were significanty affected by the foam-rubber used in the samples. The filters withcrushing strength of 0. 49 MPa and porosity of 85 % were prepared by firing at 1550℃ and then aging at 1100℃. During sintering, tbe filters shrinked about 51 %-54 % in volume.
