Handbook on the physics and chemistry of rare earths : including actinides. Volume 43 /
The rare earths represent a group of chemical elements, the lanthanides, together with scandium and yttrium, which exhibit similar chemical properties. They are strategically important to developed and developing nations as they have a wide variety of applications in catalysis, the defense industry,...
