Uranium hexafluoride (UF6) is a white solid which forms a vapor at temperatures above 56 degrees Celsius. UF6 is the compound of uranium used for the two most common enrichment processes, gaseous diffusion enrichment and gas centrifuge enrichment. It is simply called "hex" in the industry.

Yellowcake is uranium concentrate. It takes its name from the color and texture of the concentrates produced by early mining operations, despite the fact that modern mills using higher calcining temperatures produce "yellowcake" that is dull green to almost black. Yellowcake typically contains 70 to 90 percent uranium oxide (U3O8) by weight. (Other uranium oxides, such as UO2 and UO3, exist; the most stable oxide, U3O8, is actually considered to be a 2:3 molar mixture of these.)

Ammonium diuranate is an intermediate product in the production of yellowcake, and is bright yellow in colour. It is sometimes confusingly called "yellowcake" as well, but this is not a standard name.
