The sintered samples were characterized by X-ray diffraction presenting a-Al<sub>2</sub>O<sub>3</sub> and Y<sub>3</sub>Al<sub>5</sub>O<sub>12</sub> as crystalline phases. Samples with relative densities ranging from 78 to 80% and 87 to 91% were obtained depending on the composition and the compaction pressure used.  The hardness values obtained were of 1010 to 1080HV and 370-470HV, for mixes Al<sub>2</sub>O<sub>3</sub>-Y<sub>2</sub>O<sub>3</sub> having the composition with levels of 20 and 36.5wt.%, respectively.</p>}, number={1}, journal={Cadernos UniFOA}, author={dos Santos, Claudinei and Paneto, Flavio Jose and Pereira, Joaquim Lopes and Oliveira, Jean de Lima and Filho, Edson de Jesus and da Silva, Leandro Anselmo and Lima, Eduardo de Sousa and Cabral, Ricardo de Freitas}, year={2014}, month={jun.}, pages={55–60} }
