Potassium Hexa-uranate, K₂U₆O₁₉

Potassium Hexa-uranate, K₂U₆O₁₉.6H₂O, results on strongly heating a mixture of uranyl sulphate and potassium chloride; by washing out the melt with boiling water, and drying the residue in vacuo, a yellow crystalline powder is obtained. It loses all its water when heated to 300° C. The decahydrate, K₂U₆O₁₉.10H₂O, may be obtained by boiling a solution of potassium uranyl acetate.
