Abstract
IT has been known for a long time that perfectly pure tungsten cannot be used for the manufacture of filaments for electric lamps on account of its “off-setting” structure due to recrystallisation. It has been found also that recrystallisation can be essentially influenced by suitable additions. Thus, for example, thorium oxide or silicon oxide can be used with good results.
