The relative density (RD) of green

The relative density (RD) of green TiO2 pellets prepared by dry pressing was about 0.55. After rHLPS process, the obtained final densities of BaTiO3 samples are given in Table 1. As expected, the relative density of the final components was enhanced with increasing reaction time and temperature. The sample coded as BT2 which was subjected to rHLPS at 240 °C for 72 h demonstrated the highest relative density reaching 86.8%, resembling the previous studies [3]. The XRD plots obtained from whole set of samples are given in Fig. 1, exhibiting clearly similar diffraction features between each other; reference reflection marks for tetragonal BaTiO3 (ICDD PDF# 00-005-0626) are also reported on the bottom of the plot, and the occurrence of other peaks belonging to residual TiO2 is visible.
