Abstract: A wear-resistant element is configured to be mounted on a comminuting device or a silo. The wear-resistant element may be formed from a ceramic that comprises yttrium-stabilized, tetragonal polycrystalline zirconia (TPZ). The TPZ makes up a proportion of the ceramic of at least 60% by volume, in some cases at least 80%, or even 95% to 100%. The ceramic may have a porosity of less than 5%. The ceramic may have a ratio of monoclinic to tetragonal zirconia of 10% to 40%. An yttrium-stabilized zirconia of the ceramic may have a grain size D50 of less than 1.5 ?m. The ceramic may have an yttrium content of 2 to 4 mol % Y2O3.

Abstract: A wear-resistant element can be partially inserted into a recess in a surface of a wear area of a comminuting device. The wear-resistant element has a fastening region that can be connected to the recess in the surface of the wear area. The wear-resistant element may also include a wear region that protrudes at least partially from the surface of the wear area. The fastening region may comprise metal. The wear region has a shell and a core arranged inside the shell. The core is comprised of metal, and the shell is comprised of ceramic. The ceramic contains yttrium-stabilized, tetragonal polycrystalline zirconium oxide (TPZ). The TPZ makes up at least 60% by volume of the ceramic in the shell.

Abstract: A wear-resistant element for partially inserting into a recess in the surface of a wear surface of a comminuting device. The wear-resistant element has a fastening region, which is connectable to the recess in the surface of the wear surface and a wearing region, which protrudes at least partially from the surface of the wear surface. The fastening region includes a material that is less wear-resistant than the material of the wearing region, wherein the wearing region extends beyond the fastening region at the level of the wear-resistant element.

Abstract: A wear-resistant element for partial insertion into a recess on the surface of a wear area of a comminuting device. The wear-resistant element includes particles made of a highly wear-resistant material which are embedded in a matrix material.
