Abstract: | A dispersion-hardened material with average flexural strength 580 ± 40 MPa, which is a promising building material, has been fabricated by introducing a CaO-ZnO-Al2O3-SiO2 eutectic additive and tetragonal zirconium dioxide into aluminum oxide synthesized by calcining the hydroxide. The sintering temperature of this ceramic is 1550°C. The properties of the eutectic of this system are analyzed, and the optimal liquid-phase composition which gives intense sintering of the aluminum oxide is determined. __________ Translated from Steklo i Keramika, No. 4, pp. 12–15, April, 2007. |
