High-pressure chamber measurements

Summary, in English

Results from the design of a high-pressure chamber and its components, recently developed at the Lund Institute of Technology, are presented. The results show that at high pressures, when the lubricants have solidified, the density varies linearly with the pressure and the shear strength also increases nearly linearly with pressure. This is also true for the investigated gasses when they are compressed through the liquid into the solid state. Also waxes, which are solid at room pressure and temperature, show the same type of linearity. The high-pressure chamber has been used for pressures up to 3.3 GPa for a large number of compression experiments in the present form. It has been used for compressibility, shear strength, and viscosity measurements, and gasses, liquids, semi-solids (greases), and solids have been investigated.
