| 摘要 |
<p>The present invention relates to a ceramic filtration membrane with a porous support (1) formed by sintering aluminum oxide particles and metal oxide particles (e.g. silica/ titania) at a temperature greater than 1300°C and less than 1500°C, comprising fine aluminum oxide particles with a particle size of less than 10 µm, and coarse aluminum oxide particles with a particle size of 20 µm-150 µm, where the fine aluminum oxide particles represent a percentage by weight of 3%-10% with respect to the total weight of the porous support (1), the porous support (1) having a porosity greater than 28% with a pore size of 1 µm-7 µm, bending strength greater than 45 MPa and suitable chemical resistance, giving rise to ceramic filtration membranes with ceramic layers having a pore size of 1 nm to 1000 nm.</p> |
