Mit zunehmender Tiefe nimmt die Erdtemperatur zu. Im fl�ssigen inneren Erdkern herrschen Temperaturen von 3000 bis 6000 K. Durch W�rmeleitung entsteht ein W�rmestrom zur kalten Erdoberfl�che. Nur an wenigen Stellen in der oberen Erdkruste wird Erdw�rme durch Wasserund Dampfstr�mungen an die Oberfl�che bef�rdert. Die vom Erdkern abgegebene W�rme wird zu etwa ...

Ammonium uranate (AU) powders were precipitated from a uranyl nitrate solution using gaseous ammonia to determine the effect of pH of precipitation on their composition and morphology. Increasing pH of precipitation increased the ammonia and nitrate conte...
Procedures for preparation of uranic compounds for spectrographic examination are described. Included are methods for UO/sub 2/ powder and pellets, and uranyl nitrate liquors, (J.R.D.)
The uranates of monovalent thallium were isolated by dry methods. The thermogravimetric study of the reactions defined the formation mechanism of these uranates. The uranates formed were the monouranate Tl/sub 2/UO/sub 4/, diuranate Tl/sub 2/U/sub 2/O/sub 7/, and triuranate Tl/sub 2/U/sub 3/O/sub 10/. Reduction of the ...
Die Nutzung der Kernenergie ist untrennbar mit dem Element Uran verkn�pft. Da die Umwandlung eines Elements in ein anderes auf chemischem Weg nicht m�glich ist, muss das heute vorhandene Uran durch kosmische Prozesse vor Entstehung der Erde entstanden sein. Reines Uran ist ein silberwei� gl�nzendes, relativ weiches ...
ABS>The products formed by the cold reaction of hydroxide solutions of calcium, lithium, sodium, and potassium with uranyl saIts in solution were studied by potentiometry, conductimetry, and chemical analysis. The results show, in the order of increasing saturation by the bases, a hexanuclear complex of uranium, a hexanuclear uranate, and a diuranate. The line ...

Uranium ore from Radium Hill, South Australia was leached with hot sulfuric acid solutions and the uranium recovered from solution by uranous phosphate precipitation or by use of anion exchange resins. 94 to 98% of the uranium was recovered at a grade of 52 to 65% U3O6 by uranous phosphate precipitation.

Because recent experience at the Savannah River Plant revealed the pseudo-hexagonal uranates Na2U2O7 and Na6U7O2 will react exothermically in the solid state with aluminum, a systematic thermal study of the aluminothermic reactions of the three crystal classes of uranates and their relationships was begun at the Savannah River Laboratory. This paper ...

A novel easily handled substantially particulate ammonium uranate with a mean diameter between 30 and 150 micrometers, an apparent untamped bulk density of 2 to 2.8 g/cm/sup 3/, and a flowability measured on the Carr scale equal to or greater than 95, with a low sulfate ion content between 0.5 and 1%, is calimed together with a fluidized bed process for preparing such ammonium ...
A method is described of producing uranium dioxide powder for the fabrication of nuclear fuel from acidic solutions containing uranyl nitrate, comprising the sequence of steps of: (a) continuously reacting an acidic aqueous solution of uranyl nitrate with ammonium hydroxide added in less than stoichiometric amount for complete uranium precipitation, neutralizing any free acid and precipitating a ...
