Silicon carbide samples containing 10 mol% Y2O3:Al2O3 (1:3 and 1:4) were prepared, compacted and sintered at 1750, 1850 and 1950 °C in a graphite resistive furnace. Thermal shock resistance was evaluated after each thermal cycle performed at 600, 750 and 900 °C followed by abrupt cooling in water. Samples with two Y2O3:Al2O3 proportions did not show major differences when sintered at the same temperature, though, rising the sintering temperature improves Y2O3:Al2O3 modified-SiC thermal shock resistance.103-108openAccessceramicsdilatometryfractureshardnesshot pressingmechanical propertiesmicrostructurescanning electron microscopysilicon carbidessinteringthermal shockx-ray diffractionArtigo de periódico88110.4028/www.scientific.net/MSF.881.103
