The Fixation of Atmospheric Nitrogen

Sam Eyde
1909 Scientific American  
MORE than a hundred years ago, Priestley and Caven dish observed that the oxidation of atmospheric nitro gen took place on heating in an electric flame, and men like Sir William Crookes and Lord Rayleigh have, with others in recent years, given valuable contribu tions to the subject. With r' eSpect to later experi ments before those of Birkeland and Eyde, which are of a more practical' nature, the work which Lovejoy and Bradley have done should be mentioned as very important. Time will not

In shortly describing the difference between previous methods and that of Birkeland-Eyde, it must suffice to say that the latter have applied large quantities of electric energy in the electric arc, and have found out the best method of doing this, while it was previously believed that it was small quantities of energy that gave relatively the best results. It is on that assumption that the apparatus employed by them was constructed. Thus the invention ()f Btrkelami"Eyde completely revolution ized the theory of the process of atmospheric combus tion. BY SAM EYDE. By bringing great, quanti ties of energy into the elec tric arc, and finding the most suitable electric condi tions and most serviceable types of furnace, Birke land-Eyde created the synthetical nitrate industry.
