Preparation of Be7 Without Inert Carrier

Description: After bombardment with deuterons, Li metal was dissolved with dilute acid. From this solution Be7 was precipitated as Be(CH)2 on Fe carrier using NH4CH. The contaminates remained in the filtrate. After repeated precipitations in the presence of appropriate holdback carriers, the Fe was extracted with iso-propyl ether, leaving the pure Be7 solution.

The Reaction Of Nitrogen With Thorium And The Diffusion Of Nitrogen In Thorium

Description: At elevated temperatures both oxygen and nitrogen react with thorium. In its fabrication, such operations as melting, forging, roiling, swaging, and the like are commonly employed. We would like to know the precautions that must be preserved to prevent contamination of the metal during the various operations.

The PH of Uranyl Sulfate-Uranium Trioxide Solutions (Information Report)

Description: Although uranium trioxide is relatively insoluble in water, a substantial quantity will dissolve in uranyl sulfate solutions. The oxide, being basic in nature, raises the PH of the solution. This change of PH has been measured up to 60' C and can, with existing equipment, be measured up to 90"C. No work has been done with glass electrodes above this temperature, and the hydrogen electrode will not function in highly oxidizing media.

The Surface Tension of Aqueous Uranyl Sulfate Solutions Between 20' And 75'C

Description: The surface tension of aqueous uranyl sulfate solutions, ranging in concentration from 0.175 molal to 2.340 molal, has been measured at 20', 30', 45', 60' and 75'C. The surface tension increases continually with increasing temperature, becoming in the most concentrated solutions about six percent greater than that for water at the same temperature.

Apparatus For Determining The Physical Properties Of Solutions At Elevated Temperatures And Pressures (Information Report)

Description: Detailed descriptions are given of the apparatus designed and assembled at Mound Laboratory for the investigation of the density, viscosity, surface tension and vapor pressure of aqueous uranyl sulfite solutions at temperatures up to 250'C and pressures up to 2,500 pounds per square inch.

The Two Group Theory Of Piles With Multiple Reflectors

Description: The two group theory of infinite slab piles with a single reflector involves six boundary conditions and the evaluation of the determinant of the fourth order to obtain the equation for the determination of critical pile size.

The Preparation Of High-Purity Thorium By The Iodide Process

Description: The preparation of massive thorium of high purity, in lots of several hundred grams each, by the van Arkel - de Boer (iodide) process is described. Substantial reduction in the nonmetallic content of the deposits over that of the feed material was obtained. Optimum conditions for deposition were determined.
