Abstract
We have constructed a low cost isostatic press for operation at 150 MP a (1500 bar) that can also perform considerable work on the volume of the sample. It consists of two stainless steel cylinders filled with w ater. Pressure is created by cooling the water below 0 degrees C using the fact that when ice forms the pressure rises since the solid phase has a larger volume than the liquid phase. Using this press we have f abricated YBa2Cu3O7 rods of 60% theoretical density.
