FORMATION OF SAMPLE FOR MEASURING PHYSICAL PROPERTY OF MOLTEN SALT

摘要

PURPOSE:To easily take out the solidified salt at the lower edge of a pipe for shaping a sample by vertically inserting the lower edge of a pipe for shaping a sample into a molten salt, closing the upper edge of the pipe, and then carrying out the pulling, cooling and solidification. CONSTITUTION:Into a container 1 heated by a heater 8, a molten salt 2 far a sample formed to an aimed composition is input, and the lower edge of a pipe 3 for shaping the sample is inserted up to a necessary depth vertically to the liquid surface. The pipe 3 for shaping the sample is heated sufficiently by the molten salt 2 for the sample, and if the salt intrudes inside the pipe 3 for shaping the sample, the upper edge of the pipe 3 for shaping the sample is closed by a cock 4, and then the pipe is pulled up from the molten salt 2 for the sample, and the molten salt for the sample taken into the pipe 3 for shaping the sample is cooled and solidified. After the molten salt for the sample is solidified, the cork 4 is demounted, and a rod 6 for pushing out the sample salt is inserted from the upper edge of the pipe 3 for shaping the sample, and a sample salt 5 in pellet form is pushed out. The taken-out sample 5 in pellet form is introduced as it is into a cell 7 for measuring the physical property, and the sample salt is heating-molten in a physical property measuring device for the molten salt.
