“…Porous light weight refractory materials have been attracted great attentions due to the importance in the ceramics, glass, iron and steel industry. Mullite retains a significant portion of its room temperature strength at elevated temperatures and displays very high creep and thermal-shock resistance [1][2][3][4][5][6]. Therefore, mullite is one of the very important ceramic materials because of its potential application in refractories.…”

“…The mullite ceramics have had and will continue to have a significant role in the development of traditional and advanced ceramics [3][4][5][6]. Mullite is the only stable crystalline phase in the aluminosilicate system, under normal atmospheric pressure at room through elevated temperatures [3].…”

Materials from the Al 2 O 3 -SiO 2 -ZrO 2 and the Al 2 O 3 -SiO 2 -ZrO 2 -TiO 2 systems have several high temperature applications because they present the good refractoriness, chemical inertness, adequate mechanical and thermo-mechanical behaviors with a relatively good cost: performance ratio. In this work stoichiometric (3:2:1) molar incompatible mixtures of alumina (Al 2 O 3 ), zircon (ZrSiO 4 ) and titania (TiO 2 ) were slip casted and sintered in a 1300-1500 1C temperature range in order to obtain mullite (3Al 2 O 3 Á 2SiO 2 ), zirconia (ZrO 2 ) and zirconium titanate (ZrTiO 4 ) dense triple ceramic composite.Both sintering and reaction occurred after the thermal treatments. Reaction progress and densification evolutions were established. Dense Triplex composite materials were achieved after 1500 1C treatments. The reaction-sintering was followed by XRD, TG-DTA, and dilatometry. Densification started at 1100 1C and the chemical reactions only started above 1300 1C. Aluminum titanate (Al 2 TiO 5 ) was found to be an intermediate of the reaction after 1400 1C treatments. Materials treated below 1300 1C presented a partial densification of the unreacted starting powders. Resulting ceramic materials were characterized. The crystalline phases were evaluated, as well as the texture properties. The achieved microstructure consisted in interlocked multiphase ceramic with zirconia (monoclinic) grains. The achieved Hv and K IC reached 9 GPa and 4.3 MPa m 1/2 respectively. The dense and interlocked ceramic microstructure and relative high mechanical properties of the developed material encourages several high temperature applications. Finally it can be pointed out that after 1500 1C treatments some detrimental grain growth was observed.

“…Among zirconia based ceramics, mullite-zirconia-zircon (3Al 2 O 3 .2SiO 2 -ZrO 2 /ZrSiO 4 ) multicomposites (MZz) are of great technological interest due to their applications in glass and steel industries [7][8][9][10][11][12]. The MZz multicomposites exhibit excellent corrosion and thermal shock resistances and enhanced mechanical properties [13,14].…”

In the field of refractory materials, ceramics containing mullite-zirconia are the basis of those most used in the industry of glass and steel. It is known that the addition of zircon improves the behavior of the refractory used in service. Knowing that some mullite-zirconia composites properties as fracture strength and the elastic modulus E are associated with the material microstructure integrity, the eventual thermal decomposition of zircon into zirconia and silica could seriously alter the material elastic properties. In this paper the phase content of a series of mullite-zirconia-zircon (3Al 2 O 3 .2SiO 2 -ZrO 2 -ZrSiO 4 ) composites is determined at atomic level via perturbed angular correlations (PAC) and compared with that derived from the long range X-ray diffraction technique. PAC results on the asprepared materials indicate that all nominal zircon is present and that it involves two types of nanoconfigurations, one of them describing aperiodic regions. The
