FIELD: chemistry.
SUBSTANCE: invention relates to catalysts for the oxidation of ammonia in a block honeycomb structure comprising iron, aluminium, silicon oxides and stabilising additives, with the following ratio of components: iron oxide - 65-80; aluminium oxide - 19-30; silicon oxide 0.01-5, stabilising additive - 1-16. Moreover, as a stabilizing additive, the catalyst contains mixed oxides with the cordierite structure of the general formula: [(2-x)MgO⋅xMe1O]⋅[(2-y)Al2O3⋅yMe22O3][(5-z)SiO2 zMe3O2], where x=0-2; Me1=Ca, Na, K, Mn, Fe or mixtures thereof; y=0-0.5; Me2=Mn, Fe; z=0-0.5; Me3=Ti.
EFFECT: high strength and thermal stability, achieved due to additives introduced into the block catalyst of honeycomb structure from affordable and cheap raw materials.
