“…Interestingly, it should be noted that already in 1940, barium hydroxide solutions and titanium alkoxides were already known to produce BaTiO 3 at a very moderate temperature of 80 °C. [183] Nowadays, in a typical synthesis, barium nitrate (Ba(NO 3 ) 2 ) and NaOH are dissolved in water and then mixed with a butanol solution containing titanium butoxide (Ti(OBu) 4 ) and oleic acid (C 17 H 33 COOH)). Solvothermal treatment at 135 °C for 18 h then leads to very regular cubic nanocrystals with a mean side length of 22 nm.…”

With the miniaturization of electronic‐based devices, the foreseen potential of new optical nanoprobes and the assessment of eventual size and shape effects, elaboration of multifunctional noncentrosymmetric nanocrystals with ferroelectric, pyroelectric, piezoelectric, and nonlinear optical properties are the subject of an increasing research interest. Here, the recent achievements from the solution‐based methods (coprecipitation in homogeneous and nanostructured media, sol‐gel processes including various chemistries and hydro/solvothermal techniques) to prepare 0‐D perovskite and nonperovskite oxides in the 5–500 nm size range are critically reviewed. To cover a representative list of covalent‐ and ionic‐type materials, BaTiO3 and its derivatives, niobate compounds (i.e., K/Na/LiNbO3), multiferroic BiFeO3, and crystals of lower symmetry including KTiOPO4 and some iodate compounds such as Fe(IO3)3 and La(IO3)3 are systematically in focus. The resulting size, morphology, and aggregation state are discussed in light of the proposed formation mechanisms. Because of a higher complexity related to their chemical composition and crystalline structures, improving the rational design of these multifunctional oxides in terms of finely‐tuned compositions, crystalline hosts and structure–property relationships still need in the future a special attention of the research community to the detailed understanding of the reaction pathways and crystallization mechanisms.
