In this paper, attempts are made to correlate the temperature of spontaneous combustion of rare-earth metal (REM) powders with the oxidation reaction mechanism in air. Tests were made on the three most oxidation-resistant powders, scandium, yttrium, and lanthanum. The powders were prepared by grinding the solid metals in an atmosphere of purified argon, with subsequent sieving. The dimensions of the particles in the test samples ranged from 50 to 250 micrometers. It is found that the oxidation… Expand

Importance of Measuring Lanthanides
For a long time, the presence of lanthanides in samples was taken for granted. The widespread applications of the elements in various areas have however shifted this paradigm. This has beenExpand
