“…Therefore, the increasing calcination temperature will trigger a decrease in surface energy. As a result, the small particles will combine to form larger particles [15,19,20]. These result in line with the X-ray diffraction analysis.…”

Abstract. Recently, Na2/3[Fe1/2Mn1/2]O2 has received attention as a potential candidate material for cathode sodium-ion batteries. However, this material was synthesized by a solid-state process, resulting in larger particle size and nonuniform morphology. The larger particle size will sluggish the Na ion diffusion. Here we report the synthesis of Na2/3[Fe1/2Mn1/2]O2 using a simple sol-gel process. The X-ray diffraction revealed that the sample was identified as Na2/3[Fe1/2Mn1/2]O2 with a hexagonal crystal structure. However, the impurities are formed at diffraction angles of 36.28°, 45.03°, and 51.23°. Calcination temperature affects the formation of the crystal phase, grain growth, morphology, and particle size. Our findings provide valuable insight into the development of Na2/3[Fe1/2Mn1/2]O2 material with desirable properties. Keywords:Sol-Gel, Solid State, Grain Growth, Calcination, Na2/3[Fe1/2Mn1/2]O2

“…It is well known that the phase formation during the grain growth is controlled by the mobility of the atoms. Moreover the phase formation is affected by synthesis parameters as substrate temperature and degree of ionization [15] . The crystal size was calculated using the Scherrer equation as seen in equation 1 [16].…”

“…The mobility of atoms or molecules on the surface significantly increases with increasing the T sub value [ 14 ], which allows the atoms to easily jump to stable configurations [ 15 ]. Thus, the structure of glassy films can be changed by changing the T sub value without the significant modification of the glassy structure [ 16 , 17 , 18 ]. As such, the modification of the T sub value during the process of vapor deposition is an effective method to investigate the influence of structural heterogeneity on the macroscopic properties.…”

The structure of Cu50Zr50 and Co56Ta35B9 metallic glass thin films (MGTF) was effectively tailored via various applied substrate temperatures by means of the magnetron sputtering technology. Obviously enhanced hardness and elastic modulus are achieved by different compositional MGTFs by increasing the substrate temperature. Compared with the CuZr MGTFs, the CoTaB MGTF deposited at 473 K displays the smaller strain-rate sensitivity exponent, m, and a weaker spectrum intensity based on the nanoindentation creep test, suggesting its better creep resistance. In addition, the STZ volume of the CoTaB MGTF significantly decreases after depositing at higher temperature. According to the nano-scratch analysis, the CoTaB MGTF at the substrate temperatures of 473 K performs the shallower scratch width and the larger H3/E2 value, indicating its better tribological property.
