  • Selenium (Se)
    Selenium (Se)

    Selenium is a non-metallic element that exists in three forms: black glass, red crystal, and gray metal. First commercialized as a glass coloring agent to replace manganese during World War I, selenium is used today in small amounts in a wide range of applications, including electronics, pigments, photographic X-ray rectifiers, photovoltaics, alloys, and pigments. Recently, its areas of application have gradually expanded to include additives for producing high-purity manganese (Mn), materials for generating solar power (copper indium gallium selenide solar cell, or CIGS), and materials for thermo-electric semiconductors.

  • Tellurium (Te)
    Tellurium (Te)

    Tellurium is a type of rare metal that is mixed in small amounts in natural sulfides. It is a silvery-white metalloid with a tin-like appearance. It has chemical properties similar to those of selenium and sulfur, and is generally used in alloys, rubber curing agents, and thermoelectric semiconductors. LS MnM produces 99.99% pure tellurium granules and sells them in 10kg units. Our 4N (99.99% in purity) tellurium manufacturing technology is acclaimed for its technological prowess, having been selected as a project of excellence at the 2009 LS Group R&D Presentation Contest.

  • APR (NH4ReO4)
    APR (NH4ReO4)

    APR stands for ammonium perrhenate, the chemical formula of which is NH4ReO4. This white, water-soluble powder, can be processed to obtain rhenium. Rhenium is a silvery-white lustrous metal with the highest melting point second only to tungsten and carbon, and the highest boiling point among all the elements. Due to these properties, it is mainly used in industrial sectors that require durability against factors like high temperature and abrasion. Usually processed as an alloy rather than rhenium itself, most of its demand comes from the aerospace sector, which accounts for more than 70% of the entire demand. It is also used as a catalyst in the refining process of petroleum.
