Powders for producing hard materials in short reaction times are provided, especially for use in electric arc spraying. The powders are produced by bonding metallic and non-metallic starting materials to one another by spray-drying or agglomeration, using an organic or inorganic binder. The metallic starting materials are selected from the group consisting of Al, Ni, Ti, Cr, Mo, V, Zr and Ta, whereas the non-metallic starting materials are selected from the group consisting of Cr3C2, WC, C, SiC, TiB2, CrB2, B4C, TiC, VC, TiN and Si3N4. In this manner, the metallic and non-metallic starting materials react exothermically during electric arc spraying to produce a hard substance.
