It is prepared by dissolving UO3 in H2SO4. It has found use as a negative stain in microscopy and tracer in biology. The Aqueous Homogeneous Reactor experiment, constructed in 1951, circulated a fuel composed of 565 grams of U-235 enriched to 14.7% in the form of uranyl sulfate. The acid process of milling uranium ores involves precipitating uranyl sulfate from the pregnant leaching solution to produce the semi-refined product referred to as yellowcake.[1] Radioactivity was discovered using potassium uranyl sulfate, K2UO2(SO4)2.
