WebbAmong the different synthetic routes to prepare complex multi-component oxides, the Pechini-type polymerizable complex (PC) method can be highlighted [ 4 , 5 ]. The PC method allows for very high stoichiometric control, leading to obtaining complex multi-component oxides, such as BaTiO 3 [ 4 , 6 ], SrTiO 3 [ 4 , 7 ], KTiNbO 5 [ 5 ], SrBi 2 Ta 2 O 9 … Webbglycol with citric acid. Originally this method is known as the ‘Pechini process’ invented by Maggio Pechini in 1967, where a polyesterification occurs between citric acid and ethylene glycol, forming a viscous liquid of extended covalent network.

For single cation systems like SiO2 and TiO2, hydrolysis and condensation processes naturally give rise to homogenous compositions. For systems involving multiple cations, such as strontium titanate, SrTiO3 and other perovskite systems, the concept of steric immobilisation becomes relevant. To avoid the formation of multiple phases of binary oxides as the result of differing hydrolysis and condensation rates, the entrapment of cations in a polymer network is an effectiv…
