The gaseous compound used to carry out the diffusion is UFg. Various physical and chemical properties of UFg make it the only known suitable compound. It is a solid at room temperature consequently, the diffusion plant had to operate at temperatures and pressures to maintain UFg in gaseous form. Although it is a stable compound, UFg is extremely reactive with water, very corrosive to most common metals, and incompatible with organic materials (e.g., lubricating oils). This chemical activity dictates the use of metals such as nickel and aluminum, and means that the entire process flow system must... 

Two substances which have no hazardous reactivity properties in themselves can become dangerous when mixed. Certain groups of chemicals are likely to react with common substances such as air, water, acids, alkalies, and metals. Information about the possibility of such reactions is available in manuals on hazardous chemical reactions [35, 61, 62]. Examples of substances having incompatibility hazards when mixed are shown on Table 2.14. Applications of CHETAH to mixture instability determination [63,64] and to binary incompatibility [65] have been published.
