| Popis: | Undoubted leadership among catalytic materials for the purification of exhaust gases is occupied by composite cermets. Creation of catalytic materials for gas purification indicates that the main problem is partial or complete replacement of rare earth metals in their composition. In this regard, the creation of new permeable catalytic materials with partial or complete replacement of rare earth metals is relevant. Selection of composition and manufacturing technology is of great importance for the production of porous materials. The basis of charge for the production of porous materials is industrial waste such as metal oxides, metal powders, and polymetal ores (bastnaesite) containing rare earth cerium. Charge composition for the production of porous permeable metal-ceramic materials based on metal oxides with the addition of ground bastnaesite is proposed. The influence of bastnaesite on the physicomechanical and functional properties of materials obtained by self-propagating high-temperature synthesis is studied. It is shown that the neutralizer filters from materials with additives of bastnaesite have catalytic properties and can be successfully used in the purification of exhaust gases of internal combustion engines. |
