A method for synthesizing pollucite from chabazite and cesium chloride (open access)

A method for synthesizing pollucite from chabazite and cesium chloride

A method is described for immobilizing waste chlorides salts containing radionuclides and hazardous nuclear material for permanent disposal, and in particular, a method for immobilizing waste chloride salts containing cesium, in a synthetic form of pollucite. The method for synthesizing pollucite from chabazite and cesium chloride includes mixing dry, non-aqueous cesium chloride with chabazite and heating the mixture to a temperature greater than the melting temperature of the cesium chloride, or above about 700 C. The method further comprises significantly improving the rate of retention of cesium in ceramic products comprised of a salt-loaded zeolite by adding about 10% chabazite by weight to the salt-loaded zeolite prior to conversion at elevated temperatures and pressures to the ceramic composite.

Nitrogen fixation method and apparatus. [DOE patent application] (open access)

Nitrogen fixation method and apparatus. [DOE patent application]

A method and apparatus for achieving nitrogen fixation includes a volumetric electric discharge chamber. The volumetric discharge chamber provides an even distribution of an electron beam, and enables the chamber to be maintained at a controlled energy to pressure (E/p) ratio. An E/p ratio of from 5 to 15 kV/atm of O/sub 2//cm promotes the formation of vibrationally excited N/sub 2/. Atomic oxygen interacts with vibrationally excited N/sub 2/ at a much quicker rate than unexcited N/sub 2/, greatly improving the rate at which NO is formed.
