The invention relates to a method for producing a carbide with a toughness-increasing structure, comprising the following steps: providing a hard material powder, wherein the average BET particle size of the hard material powder is less than 1.0 mm; mixing the hard material powder with a binder powder; shaping the mixture made of hard material powder and binder powder to form a green body; and sintering the green body. The invention also relates to a carbide with a toughness-increasing structure comprising a phase made of hard material particles and a phase made of binder metal heterogeneously distributed in the carbide, which is present in the form of binder islands, wherein the carbide with a toughness-increasing structure produced after the sintering has a phase made of hard material particles with an average particle size in the region between 1 nm and 1000 nm, and the binder islands have an average size of 0.1 &#x3bc;m to 10.0 &#x3bc;m and an average distance between the binder islands of 1.0 &#x3bc;m to 7.0 &#x3bc;m.
