Hydrothermal synthesis of carbonate-free submicron-sized barium titanate from an amorphous precursor: Synthesis and characterization

Simple synthesis and characterization of SrSnO3 nanoparticles with enhanced photocatalytic activity

“…This difference has relevance to the incorporation of carbonate anions into the SrSnO 3 structure. Some studies have reported that the incorporation of carbonate ions happens easily during the synthesis of some metal oxides and thus, various attempts [22,23] have been made to interrupt this incorporation. In particular, it has been reported that SrSnO 3 also shows this phenomenon [20,21].…”

Hydrothermally synthesized BaTiO3 textured in a strong magnetic field

“…An amorphous precursor material was prepared by the peroxo-hydroxide method described elsewhere [18]. The amorphous precursor was hydrothermally treated in a stainless steel reactor in a 10 M NaOH solution at 200 1C for 24 h. After washing with demineralized water, the powder was washed in an acetic acid solution with pH 5.5 in order to remove the carbon (BaCO 3 ) contamination and calcined at 950 1C for 1 h to remove the hydroxides and to improve the tetragonality of BaTiO 3 [19].…”

Recent development on modification of synthesized barium titanate (BaTiO3) and polymer/BaTiO3 dielectric composites

“…[36] When the precursors are dried in vacuum oven at room temperature, the purity of BaTiO3 is greatly improved. [37] The BaTiO3 particles, fabricated by hydrothermal synthesis method, are found to be highly dense with the grain size controlled at 200 ~ 400 nm. [38] Kothandan synthesizes spherical BaTiO3 grains via the low temperature hydrothermal technique.…”
