Trends in the Industrial Uses for Mischmetal

  • I. S. Hirschhorn


Ronson Metals Corporation, which was founded in 1915, has witnessed all of the changes which have occurred in the uses of mischmetal (mixed rare earth metals) over the last sixty-four years. It is illuminating to note currently the drastic changes which have occurred in the last decade as compared with the present and as projected over the next ten years. These patterns are seen in Table 1.
