“…To the best of our knowledge, there have been no reports on mechanical activation of commercial strontium titanate powders to obtain nanoparticles less than 100 nm in size. There is a report of samples synthesized using a solid state reaction, followed by milling for 10-120 min, resulting in particle sizes in 100-300 nm range [23].…”

Structural changes caused by mechanical activation of SrTiO 3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 min activation, while mesopore volume and specific surface area increased accordingly. Higher activation times lead to increased agglomeration of nanoparticles to form agglomerates of around 2 µm in size, ultimately

“…This observation will promote an enlargement on surface area of SSC based composite cathode powders within a shorter processing time. The increased surface area indicates good porosity behaviour and remarkable the expansion of TPB area which subsequently magnify the cell performance of SSC-SDCC composite cathode [16,17,18]. demonstrations all major elements such as sodium, cobalt, samarium, cerium and strontium were distributed in good manner.…”

Samarium strontium cobaltite, Sm0.5Sr0.5CoO3−δ (SSC) and samarium doped ceria, Sm0.2 Ce0.8O1.9 (SDC) carbonate or (SDCC) was used as the new composite cathode powder materials. Composites cathode powder samples with different on weight percentages, 50:50 wt.% of SSC:SDCC, 60:40 wt.% of SSC:SDCC and 70:30 wt.% of SSC:SDCC were chosen to be use in this research work. The prepared samples of composite cathode powders were characterized by using high energy ball milling (HEBM) techniques for LTSOFC application. Characterizations of the composite cathode were performed through energy dispersion spectroscopy (EDS) and field emission scanning electron microscopy (FESEM) analysis. From EDS analysis shows SSC-SDCC composite cathode powders produced via high energy ball milling techniques (HEBM) or mechanochemical activation indicated that all major elements such as sodium, cobalt, samarium, cerium and strontium were well distributed among the composite cathode powders. Nonetheless, the FESEM images revealed HEBM technique can be used to prepare composite cathode powders with high homogeneity. These results showed that SSC-SDCC composite cathode powders, content with 50 wt.% of SDCC revealed a smallest of particle size with good homogeneity of particle to be us as cathode materials for LTSOFC applications.

“…The final solid product was collected and characterized. As a comparison, SrTiO 3 was also synthesized by a traditional high temperature solid state reaction of TiO 2 and SrCO 3 at 1000 °C for 4 h [23]. According to different mole ratio of Sr(OH) 2 ·8H 2 O and TiO 2 and reaction duration, the samples were denoted as S1-20, S2-20, S1-40, S2-40, S1-60, and S2-60 respectively.…”
