Abstract
A NOX sensor material includes a composition of Ba(1-X)AXFe(12-Y)BYO19. Constituent A and constituent B are doping elements. Constituent A is selected from the group consisting of Bi, La and Pb and X is a real number where 0≦X<1. Constituent B is selected from the group consisting of Al, B, Bi, Ca, Co, Cr, Cu, Er, Ga, In, Mg, Mn, Ni, Nb, Rh, Pb, Si, Sr, Ti, Ta, Zn and Zr and Y is a real number where 0≦Y<12. The NOX sensor material may be used in a sensor element of a NOX sensor.
