摘要
This invention relates to a ceramic and a cermet each having a second phase for improving toughness via phase separation from a complete solid-solution phase and to a method of preparing them. The ceramic and the cermet may have the second phase phase-separated from the complete solid-solution phase, thereby easily achieving a great improvement in toughness and exhibiting other good properties including high strength, consequently enabling the manufacture of high-strength and high- toughness cutting tools, instead of conventional WC-Co hard materials.
