Abstract:

The melting point of Li99.8 and Na99.9 was measured in the pressure range from 1 to 30,000 kgsq cm. The pressure was developed by compressing a mixture of isopentane with pentane in a superhigh pressure multiplier. The melting point was determined by the thermal analysis method with photographic recording of the cooling and heating curves of the specimen. The pressure was measured by a manganin manometer within an accuracy of or - 100 kgsq cm the temperature was measured by an iron-nichrome thermocouple within an accuracy of or - 1.5C. The melting point of Li and Na increased monotonically from 182 and 97.5 C, respectively, at atmospheric pressure to 234-248 C at a pressure of 30,000 kgsq cm. Author
