Influence of the Uniaxial Hot-Pressing Sintering Condition on Bi₄Ge₃O₁₂ Ceramic Scintillators

Figure 2

Height changes of the samples during the hot-pressing procedure using three different pressure factors. The solid black line represents the heating program. In the first stage, the sample is heated up to 840°C; in the second stage, the sample is maintained under 840°C for 4 h; and in the third stage, the sample is cooled down to room temperature.
