Hydrothermal laboratory

200 MPa line

6 externally heated cold-seal autoclaves (steel: ATS). T-P limits: 800 °C at 200 MPa or 900 °C at 100 MPa. Pressure medium: H2O. The temperature can be controlled via internal or external thermocouples, depending on capsule length. Maximum capsule diameter: 5 mm.

500 MPa line

12 cold-seal autoclaves (steel: ATS or RENE41). T-P limits: 750 °C at 500 MPa or 900 °C at 100 MPa. Pressure media: H2O (up to 10 autoclaves), or CO2 (2 autoclaves, separate pressure generation unit, to about 400 MPa). The temperature can be controlled via internal or external thermocouples, depending on capsule length. Maximum capsule diameter: 5 mm.

Rapid quench line

6 rapid quench autoclaves (steel: ATS). T-P limits: 800 °C at 200 MPa or 900 °C at 100 MPa. Pressure medium: H2O. The temperature is controlled via external thermocouples.
