A new flexible titanium foil cell for hydrothermal experiments and fluid sampling

This paper describes the design of a flexibletitanium foil cell, as well as its applications in hydrothermalexperiments and in non-contaminating storage of seafloor hydrothermal fluids. A flexible cell constructed totally from puretitanium (Grade 1) can be used in corrosive environment because of the excellent chemical stability and temperature tolerance of the material. Theoretical calculation and finite element analysis of thetitanium foil cell have been conducted to identify its flexibility and deformation mode. Two applications, i.e., hydrothermalreaction and non-contaminating fluid sampling, were introduced subsequently. The flexibletitanium foil cell was successfully tested at elevated temperature andpressure of up to 400  °C and 40 MPa, respectively, demonstrating that it could be widely used under supercriticalwater conditions.
