Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A toughened ceramic material, comprising two borides, at least one carbide, and a refractory metal; wherein the said two borides are TiB 2 and ZrB 2 ; the said carbide is from the group of SiC, B 4 C, TiC, NbC, TaC and WC; and the said refractory metal is tungsten, with a toughened ceramic material being prepared by smelting the two borides, the at least one carbide and the refractory metal together; and when the two borides, the at least one carbide and the refractory metal are heated and smelted, substantially all the refractory metal reacts with the two borides and/or the at least one carbide to form a pure ceramic structure without any metallic cemented phase.
