Ceramic membrane |
摘要 |
A method of manufacturing a semi-permeable ceramic membrane and a semi-permeable ceramic membrane made by the method, the method including providing a mixture of at least two non-metallic mineral components comprising fine particles having an effective particle size of up to 1 mu m and coarse particles having an effective particle size of 1 mu m or above, the fine particles having a higher coefficient of thermal expansion than the coarse particles, suspending the mixture of fine and coarse particles in a liquid to form a slurry, applying the slurry to a porous mould so as to form a green intermediate product, and baking or firing the green intermediate product to form a finished membrane. The finished membrane has a density distribution of the fine particles that increases in one direction (in use) across the finished membrane and a density distribution of the coarse particles that decreases in the same direction across the finished membrane. <IMAGE> |
