A technique to strengthen alumina matrix ceramics was presented, in which ZrB(2) and ZrO(2) were incorporated into the matrix ceramic in the form of Zr-O-B compounds. By detailed X-ray diffraction analysis, it was made sure that possible reactions in sintering which were beneficial to the materials design. Composites of Al(2)O(3)/ZrB(2)/ZrO(2) were fabricated and the fundamental properties of the composites such as hardness, fracture toughness and bending strength were examined. Meanwhile, the effects of Zr-O-B compounds on densification rate, mechanical properties, and microstructures of alumina matrix ceramic materials were analyzed.
