Available in PDF, EPUB and Kindle. Book excerpt: The sensitivity characteristics of a variety of Zr samples such as sponge, scrap, powder and process materials were studicd. Of particular interest was the determination of the relative seasitivity of these materials to such stimuli as impact, friction, electrostatic discharge, and heat. A study of the zirconium--water reaction at relatively low temperature was initiated. In general, scrap and sponge were relatively insensitive to impact. Only one proeess material, the distillation residue, exhibited any pyrophoric tendencies in this test. As anticipated, the majority of the samples tested were somewhat sensitive to friction. The dry distillation residues and Ca-reduced Zr powders, which had frequency rates of 100% in most cases, were the most sensitive of all the samples tested. Sponge was moderately sensitive, but the variation in sensitivity could not be correlated with either particle size or chemical impurities. Neither the Zr or Zircaloy scraps in the form of chips and turnings were very sensitive. The maierial which proved to be most insensitive to friction was the vapor phase residue. A frequency rate of zero was noted for all the samples tested. Using a condenser discharge to heat wire samples rapidly in aa inert atmosphere to a temperature well above the melting point, an attempt was made to determine the effect of stress on the pyrophoricity of Zr. It was found that the minimum energy requirements for fragmentation of a pure Zr wire are reduced by the application of mechanically induced stresses and bv the addition of chemical impurities such as C and/or H/sub 2/, Although the experimental phase of the study of the zirconium--water reaction has been barely- initiated, there is some evidence to indicate thai pre-treatment of a sample with N, at elevated temperatures does promote the oxidation reaction with steam.

Book excerpt: Massive zirconium metal scrap can be handled, shipped, and stored with no evidence of combustion or pyrophoricity hazards. Mechanically produced fine scrap such as shavings, turnings, or powders can burn but are not pyrophoric unless the particle diameter is less than 54 .mu.m. Powders with particle diameters less than 54 .mu.m can be both pyrophoric and explosive. Pyrophoric powders should be collected and stored underwater or under inert gas cover to reduce the flammability hazard. Opening sealed containers of zirconium stored underwater should be attempted with caution since hydrogen may be present. The factors that influence the ignition temperature have been explored in depth and recommendations are included for the safe handling, shipping, and storage of pyrophoric or flammable zirconium. 29 refs., 5 figs., 6 tabs.
