FIELD: process engineering.SUBSTANCE: invention relates to powder metallurgy, particularly, to charge compositions for production of porous permeable catalytic material by self-propagating high-temperature synthesis and can be used for production of filter elements. Charge with loparite contains the following components in wt %: iron scale 47.5-47.8, chromium oxide (III) 10.5-11.5, chromium 5.2-5.6, nickel 5.5-6.0, aluminium 12.3-12.5, bastnaesite ore 15-17, copper 1.6-2.0. Said porous permeable material ensures high-quality catalytic cleaning of ICE exhaust gases.EFFECT: higher resistance to dynamic and static loads.1 tbl, 1 ex |
