Meteoric iron, hydrogen

Hydrogen occurs in small quantities in Nature in the uncombined state. It is found in a state of condensation in many rocks and in some specimens of meteoric iron. It is present in the gaseous discharges from oil and gas wells and volcanoes, and is also a constituent to a very minute extent of the atmosphere... [Pg.2]

In Meteoric Iron.—An examination of certain meteoric irons, made by Sir WilUam Ramsay and Dr. Travers, showed that these contained occluded gas, and that this gas was hydrogen —... [Pg.3]

Observing that meteoric iron contains occluded hydrogen, it is interesting to note that the examination of steel shows that it also possesses this property of condensing gases. Steel of the following composition—... [Pg.4]

About 70% of the western world s supply of nickel comes from iron and nickel sulfide ores that were brought close to the surface nearly 2 billion years ago by the violent impact of a huge meteor at Sudbury, Ontario. The ore is first roasted (heated in air) to form nickel(II) oxide, which is reduced to the metal either elec-trolytically or by reaction with hydrogen gas in the first step of the Mond process ... [Pg.784]
