Ceramic materials in the system ZrO_2-TiO_2-Al_2O_3 for applications in the ferrous and non ferrous metallurgy

摘要

The well corrosion resistance of Zirconia and Titania materials are attended by an insufficient thermal shock behaviour. It will be shown that small additions (5 wt/100) of Titania in partial stabilized Zirconia and Aluminiumtitanate in Titania is decreasing the Young Modulus of Rupture and the Thermal Expansion Coefficient of both materials, so that the thermal shock resistance is increasing Strongly. The medium four point bending strength of these materials are higher than 120 Mpa Whereby the corrosion resistance has still remained.
