<p>Sintered ceramics, that may be of use in making the extremely hard tips of cutting tools, can be made from a ceramic matrix material having a ceramic refractory material incorporated therein. The application seeks to provide an improved sintered ceramic material of this general type, wherein the refractory material consists of particles of significantly different sizes and which lie at least predominantly in at least two substantially different mean particle size ranges.</p> |
