## Description

- description: 'Currently, Russian industry is consistently developing the entire
    technological chain of the rare earth elements (REE) industry: mining and extraction
    of REE obtaining metals and introducing them into high-tech production.Sazhin
    Giredmet JSC is a leading Russian research and design organization specializing
    in the development of new materials based on rare earth metals (REM), their compounds
    and alloys, high-purity substances, and semiconductor materials. An experimental
    extraction site has been created and is operating, allowing for the extraction,
    separation, and purification of REM from their solutions. The site is equipped
    with extractors (100 pcs.). At the same time, JSC Giredmet is improving technologies
    for obtaining metallic REM by metallothermic reduction of REM oxides and halides
    with the delivery of metal products to consumers, including those producing special
    products. Our enterprise uses both the legacy of Soviet science and introduces
    innovative technologies. At present, the production of REM by metallothermy methods
    (Ca, La, Li) has been implemented and launched, the estimated volume of output
    is tens of kilograms per month, with the possibility of scaling into tons. Today,
    the technology of electrolysis from oxide-fluoride melts is being implemented.
    The competencies in obtaining and purifying anhydrous REE chlorides, which are
    precursors for obtaining organometallic compounds and high-purity metallic REE,
    have been preserved and are practically applied. This has expanded the scope of
    their application for special alloys.Sazhin Giredmet JSC develops manufacturing
    technologies and produces alloys with REM as finished products in the form of
    ingots, strips and powder. One of the promising areas of development is the production
    of metal hydride alloys based on La and Ni. Gaseous hydrogen is capable of entering
    into a chemical reaction with metals and alloys, forming solid compounds. The
    reaction is reversible, which allows implementing cycles of loading and unloading
    metal hydride storage devices. The development of hydrogen storage alloy technology,
    which in addition to storing hydrogen would also act as hydrogen purifiers from
    harmful impurities (oxygen, nitrogen, water vapor) is an important part of maintaining
    a green ecology.'
