Characteristics of Depleted UF6


UF6 is a white crystalline solid at the pressure and temperature conditions normally found in storage cylinders. At normal (atmospheric) pressures, the UF6 will remain as a solid if the temperature is less than 133°F, and when heated, will convert from a solid directly to a gas.

UF6 gas is unstable in air. It reacts with water vapor in the air to form solid uranyl fluoride (UO2F2) and hydrogen fluoride (HF) gas.
