Patent number: 8221664Abstract: 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.Type: GrantFiled: December 19, 2007Date of Patent: July 17, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Guenter Zeitler, Herbert Schreinemacher, Cornelis Ronda
