CAS No. 7782-39-0 Deuterium Gas Supplier. Characteristics of Deuterium Gas

Deuterium gas, often denoted as D2, is a stable isotope of hydrogen with one proton and one neutron in its nucleus. Its CAS number is 7782-39-0. Here are some key characteristics of deuterium gas:

Characteristics of Deuterium Gas:
Molecular Formula: D2
Molecular Weight: Approximately 4.028 g/mol (compared to 2.016 g/mol for H2)
Boiling Point: At standard atmospheric pressure, the boiling point is slightly lower than that of protium (ordinary hydrogen) but still very close: approximately -249.5 °C or 23.65 K.
Melting Point: Approximately -251.4 °C or 21.75 K.
Density: At STP (standard temperature and pressure), the density of deuterium gas is slightly higher than that of protium gas.
Solubility: Like protium, deuterium gas is sparingly soluble in water.
Reactivity: Deuterium gas is less reactive than protium due to the stronger D-D bond compared to the H-H bond.
Uses: Deuterium gas is used in various applications including nuclear fusion research, as a tracer in chemical reactions, in the calibration of scientific instruments, and in the production of heavy water .
