Melting studies were made on Sn and e, and equations are given which can be used to calculate the melting pressure of these substances at any temperature to pressures of 10,000 bars. The intensifier for the generation of pressure consisted of a ram of about 4.5-in. inner diameter and 6-in. outer diameter which drives a 0.654in.- iam piston. The steel pressure cell has a 0. 5-in. inner diameter and a 3.0-in. outer diameter with a usable bore of 6-in. Pressure measurements were obtained with a manganin wire resistance gage. A 1000-w electric heater was used to heat a bath of Na, K, and Li nitrates which remained fluid below 150 C and did not cause corrosion of the steel parts immersed in it. Details of the heater and gage circuits and pressure seals are presented.
