Abstract
A toughened ceramic material includes at least one boride and a refractory metal, or at least two borides, one carbide at least, and a refractory metal. The toughened ceramic material is by means of heating and smelting the above materials. During the process of preparing the toughened ceramic material by heating and smelting, substantially all the refractory metal reacts with the boride and/or the carbide to form a toughened ceramic material with a high toughness and substantially without metallic cemented phase.
