Calcium oxide is a cheap, chalky chemical compound commonly used in the manufacturing of cement, plaster, paper, and steel. But the material may soon have a more high-tech application. "This system ...

DURING recent years a number of experimental investigations of the physics of the oxide-coated cathode have taken the form of determinations of the thermionic and electrical properties of the ...

IT has been reported 1 that the extent to which the reaction proceeds is influenced by the reactivity of the calcium oxide. The possibility that both this and the analogous reaction might be used for ...
