What is The Melting Point of Promethium?

Promethium has a Melting Point of 1,042°C (1,907 °F), which means at 1042 °C temperature it changes from a solid to a liquid state.

Promethium is a chemical element with the symbol Pm and atomic number 61. All its isotopes are radioactive; it is extremely rare, with only about 500–600 grams naturally occurring in Earth’s crust at any given time. It does not exist in nature and must be produced in the lab. Promethium was the last of the rare earth lanthanides to be discovered.

The melting point of promethium is 1042°C (1,907°F). It is the temperature at which the metal changes from a solid to a liquid state. This highly reactive, silvery metal is known for its unique properties, including its radioactive nature and its low natural abundance.

Despite its rarity and radioactive properties, promethium has several important applications, particularly in nuclear technology. For example, promethium-147, one of the isotopes of the element, is used in radioisotope thermoelectric generators (RTGs) to provide a continuous source of energy for deep-space missions, such as the Voyager spacecraft. This isotope generates heat through beta decay and converts it into electricity through thermocouples.

The melting point of promethium is an important property that affects its ability to be used in certain applications. For example, in the production of alloys, the melting point of promethium must be taken into consideration in order to determine its suitability as a component.

Similarly, in the manufacturing of nuclear fuels, the melting point of promethium can impact the efficiency of the fuel rods and the overall performance of the reactor.
