Synthesis and characterization of MTiO3(M = Mg, Ca, Sr, Ba) sol-gel

Synthesis and characterization of nanocrystalline strontium titanate through a modified combustion method and its sintering and dielectric properties

“…In solid state synthesis a single phase SrTiO 3 could be obtained only after prolonged calcinations of the reaction mixture at high temperature (>1000 • C) with repeated grindings [14]. The coarse grained powder thus synthesized also has the disadvantage that it contains agglomerated particles of different sizes with impure phases due to incomplete reactions [15]. Synthesis of advanced ceramics as nanoparticles is one of the major challenges in the development of materials processing technology and the advantages of nanocrystalline materials are superior phase homogeneity, sinterability and microstructure leading to unique mechanical, electrical, dielectric, magnetic and optical properties [16].…”

High-density NiTiO3/TiO2 nanotubes synthesized through sol–gel method using well-ordered TiO2 membranes as template

“…The fabricated dense porous material is the first example of NiTiO 3 /TiO 2 combination among several other systems, such as PbTiO 3 [23,25], SrTiO 3 [24], BaTiO 3 [20,24], etc., prepared so far. The sol-gel method using the two-end opened ATO membrane as template was a facile possible way to fabricate the NiTiO 3 /TiO 2 compound nanotubes, which opens a new avenue to prepare these composite materials by the sol-gel method.…”

“…Several methodologies, such as sol-gel [24], hydrothermal [25], sputtering [26], co-precipitations [27], solid-state reactions [28], and polymeric precursor method [29] have been proposed for synthesising crystalline MTiO 3 powders. While, MTiO 3 fabricated by these methods usually require complex equipments and complicated operation procedures.…”

The quest for single-source precursors for BaTiO3 and SrTiO3

“…Among them, BaTiO3 is a typical representative while SrTiO3 is a good candidate for insulating buffer layers for high Tc superconductors or as photocatalysts [2]. While various mixed-metal Ba-Ti species have been reported [3,4], Sr2Ti(OiPr)s(iPrOH)5 [5], originally described as a species of 1:1 stoichiometry [6], remains the only Sr-Ti species reported so far.…”
