Microstructure and thermal expansion of Al2TiO5–MgTi2O5 solid solutions obtained by reaction sintering

Identification of asymmetric constitutive laws at high temperature based on Digital Image Correlation

“…7,25 In the literature, a considerable work was devoted to the aluminium titanate ceramics analysis from a material point of view, especially on their processing, microstructure, composition and thermal expansion coefficient. [22][23][24][25][26] Studies of the mechanical properties are more rare, particularly at high temperature. [27][28][29] At room temperature, the open microcracks are willing to propagate, so that the mechanical behaviour is known to be damageable.…”

Magnesium dititanate (MgTi2O5) with pseudobrookite structure: a review

“…Since MgTi 2 O 5 has relativity high thermal stability among pseudobrookite-type phases, Al 2 TiO 5 -MgTi 2 O 5 solid solution has been investigated [17][18][19][20][21][22]. Moreover, our group has studied porous MgTi 2 O 5 as a third-generation diesel particulate filter material with well-balanced properties, such as low thermal expansion, low cost, high-temperature stability and potentially good mechanical properties [23][24][25][26].…”

Formation of Aluminum Titanate with Small Additions of MgO and SiO2

“…This because the phenomena are related to grain size, i.e., Al 2 TiO 5 becomes stable at room temperature, below a critical grain size. Also, below a certain critical grain size (which is not necessarily the same), the stresses caused during cooling become insufficient for formation of microcracks [21][22][23] . This fact controls thermal and mechanical properties of the material 22,24,25 .…”
