    • A hot axial pressing method for sintering a ceramic powder, particularly doped Gd2O2S, comprises the step of placing a first porous body (7), the ceramic powder (9) and a second porous body (7) into a mould shell (5) supported by a support (13, 14). The ceramic powder (9) is located between the porous bodies (7). Gaseous components are evacuated from the ceramic powder (9) up to an ambient pressure of less than 0.8 bar. The porous body (7) and the ceramic powder (9) are heated to a maximum temperature of at least 900° C. and are applied to a pressure up to a maximum pressure of at least 75 Mpa. According to the invention the variation in time of the heating step and the variation in time of the pressure applying step is adjusted to each other such that the mould shell 5 is held by the porous bodies (7) and/or the ceramic powder (9) in a state where the mould shell (5) and the support (13, 14) are disconnected with respect to each other.
    • 用于烧结陶瓷粉末,特别是掺杂Gd 2 O 2 S的热轴向压制方法包括将第一多孔体(7),陶瓷粉末(9)和第二多孔体(7)放置在支撑的模壳(5)中的步骤 通过支持(13,14)。 陶瓷粉末(9)位于多孔体(7)之间。 将气态组分从陶瓷粉末(9)排出至小于0.8巴的环境压力。 将多孔体(7)和陶瓷粉末(9)加热至至少900℃的最高温度,并施加至至多75Mpa的最大压力的压力。 根据本发明,加热步骤的时间变化和压力施加步骤的时间变化相互调节,使得模制壳体5由多孔体(7)和/或陶瓷粉末(9)保持 )在模壳(5)和支撑件(13,14)之间相对于彼此断开的状态。
