Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
In this section, the elemental forms of rare-earth elements are iron gray to
silvery lustrous metals that are typically soft, malleable, ductile, and usually reactive,
especially at elevated temperatures or when finely divided. rare-earth elements are
examined in terms of physical and chemical properties. This makes them essential
components of diverse defense, energy, industrial, military technology, and low-carbon
technologies. Furthermore, REEs are rapidly being used in magnet applications. For
example, magnets produced by Neodymium-iron, the strongest known type of magnet,
are used widely. Thus, their application areas vary from the electronic to glass industry.
Also, information about the sources of rare-earth elements is given in this part.
