Abstract

A1₂O₃-5mass%Y₃Al₅O₁₂ (YAG) composites were fabricated by the coprecipitation method. The bending strength of sintered bodies was estimated. The YAG particles were homogeneously dispersed into the Al₂O₃ grains hindering the matrix grain growth. The bending strength of the composites was enhanced as compared to alumina monolithic materials. Both the processing and mechanical properties of the developed composites are discussed.
