Decomposition of Al2TiO5-MgTi2O5 solid solutions: a thermodynamic approach

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].…”

A Non-Hydrolytic Sol-Gel Approach for the Preparation of MgxAl2(1-x)Ti(1+x)O5Powders

“…The synthesis was monitored by means of 13 C NMR spectroscopy, a technique which was successfully used to study the preparation of Al 2 TiO 5 thin films via a conventional sol-gel route [7]. Figure 1(a) shows the 13 C spectrum of the initial Al(OsBu) 3 and Ti(OiPr) 4 solution in toluene.…”

“…13 C NMR spectra were recorded on a Bruker AM 400 spectrometer operating at 100.56 MHz. Chemical shifts are given in ppm from tetramethylsilane (TMS) and referenced against solvent signals.…”

“…This paper reports the synthesis and characterization of magnesium doped aluminium titanate of composition Mg 0.6 Al 0.8 Ti 1.6 O 5 . The indicated composition was targeted for its reported high thermal stability [13,14].…”

Mechanical strength and electrical conductivity of reactively-sintered pseudobrookite-type Al₂TiO₅–MgTi₂O₅ solid solutions

“…The CTE of polycrystalline Al 2 TiO 5 ceramics, however, was rather small as an oxide, typically reported as <2.0 © 10 ¹6 /°C. 5),6) Despite the fascinating low thermal expansion behavior, Al 2 TiO 5 is not so thermally stable and decomposes into Al 2 O 3 and TiO 2 below the equilibrium temperature of 1280°C, 7) which limits the applications of Al 2 TiO 5 , particularly in reducing atmosphere.…”
