Zippeite - Wikipedia
网页Zippeite is a hydrous potassium uranium sulfate mineral with formula: K 4 (U O 2) 6 (S O 4) 3 (O H) 10 ·4 (H 2 O). It forms yellow to reddish brown monoclinic -prismatic crystals with perfect cleavage. The typical form is as encrustations and pulverulent earthy masses.

网页Zippeite. Delta Mine, San Rafael Swell Mining District, Emery County, Utah, USA. 6.4 x 5.1 x 4.5 cm. The yellow patches you see here are probably zippeite (darker yellow) and uraninite (uranium oxide- lighter yellow) - this specimen came from the Delta Mine in Utah, which was mined almost exclusively for uranium; this specimen went to the well ...

Thermodynamic studies of zippeite, a uranyl sulfate common in …
网页2016年12月30日 · Zippeite is a potassium uranyl sulfate mineral that forms on uranium mine wastes and that may be important in nuclear waste disposal. Little is known about its thermodynamic properties. In this study, we synthesized zippeite, K 3 (H 2 O) 3.3 [(UO 2) 4 (SO 4) 2 O 3 (OH)], and measured its thermodynamic properties.
