dc.description.abstract | The importance of rare metals in scientific and technical progress has been steadily increasing since the beginning of this century. At the present time it is difficult to conceive any field of modern science which does not, to a more or less extent, make use of rare metals, their alloys or diverse compounds. Atomic power engineering, radio electronics, aviation and rocket engineering, mechanical engineering, the instrument-making and chemical industries constantly increase the number of rare metals that they use as well as the requirements for their purity. | en |
