A THERMOBALANCE FOR STUDYING THE CHLORINATION OF PLUTONIUM DIOXIDE WITH PHOSGENE

摘要

An automatic recording thermobalance for studying the chlorination of plutonium dioxide with phosgene is described. The highly toxic and corrosive nature of these materials imposed restrictions on the construction and operation of the thermobalance.nThe instrument operates on the deflection balance prin¬ciple in which the extension of a precision quartz helix spring is measured by a linear variable differential trans¬former. Experimental results from the gas-solid reaction between phosgene and plutonium dioxide are discussed.
