MOUND LABORATORY PROGRESS REPORT FOR JANUARY 1961

PDF Version Also Available for Download.

Description

Work was begun to determine the physical properties of mica-filled diallyl phthalate. Both the impact and tensile strength values compared favorably wlth asbestos-filled DAP formulatlons. The tensile values compared with the upper limit tensile strength values for asbestos-filled formulations. Adiprene-ferric acetyl acetonate-polyol systems were developed as adhesives and their properties studied. Sources of kilogram quantities of Th/sup 2//sup 3//sup 0/ were investigated. The samples were analyzed by a direct CeF/sub 3/ precipitation procedurc or by a tributyl phosphate-cerium procedure. The half- life of Ra/sup 2//sup 2//sup 3/ was found to be 11.3700 plus or minus 0.0065 days. Differential thermal analyses ... continued below

Three preilminary determinations of the density of molten cerium were made by the vacuum pycnometer method. An average value of 6.58 was obtained. Leaching tests in water and in 0.1N HCl were continued on fibers of an experimental glass containing 10 wt.%n plutonium oxide. (M.C.G.)
