  • CERIUM

    Harga :

    Minimal Order :

    Cerium, atomic no. 57, symbol Ce, weight at 140.12, is the most abundant of the rare earths. It is strongly acidic and a strong oxidizer. In glass industry, it is considered to be the most efficient glass polishing agent for precision optical polishing. It is also used to decolorize glass by keeping iron in its ferrous state. Cerium is also used in a variety of ceramics, including dental compositions and as a phase stabilizer in zirconia-based products. In catalytic converters Cerium acts as a stabilizer for the high surface area alumina, as a promoter of the water-gas shift reaction, and as an oxygen storage component. It is used in FCC catalysts containing zeolites to provide both catalytic reactivity in the reactor and thermal stability in the regenerator. In steel manufacturing, it is used to remove free oxygen and sulfur.

    Minimal Order :

    Praseodymium, just 4% of the Lanthanide content of Bastnasite, is a common coloring pigment. Along with Neodymium, Praseodymium is used to filter certain wavelengths of light. Praseodymium is used in photographic filters, airport signal lenses, and welder’s glasses. Its color allows production of various pigments used in coloring products such as ceramic tile and glass. Vibrant yellow ceramic tiles and glasses most likely contain Praseodymium and certain premium quality mirrors and lenses also depend on Praseodymium.

  • YTTERBIUM

    Harga :

    Minimal Order :

    Ytterbium resembles Yttrium in broad chemical behavior. The metal, when subject to very high stresses, increases its electrical resistance by an order of magnitude and is used in stress gauges to monitor ground deformations caused, for example, by nuclear explosions. Ytterbium metal has possible use in improving the grain refinement, strength, and other mechanical properties of stainless steel. One isotope is reported to have been used as a radiation source substitute for a portable X-ray machine where electricity is unavailable. Few other uses have been found.

  • SAMARIUM

    Harga :

    Minimal Order :

    Samarium, along with other rare earths, is used for carbon-arc lighting for the motion picture industry. SmCo5 has been used in making a new permanent magnet material with the highest resistance to demagnetization of any known material. It is said to have an intrinsic coercive force as high as 2200 kA/m. Samarium oxide has been used in optical glass to absorb the infrared. Samarium is used to dope calcium fluoride crystal for use in optical lasers or lasers. Compounds of the metal act as sensitizers for phosphors excited in the infrared; the oxide exhibits catalytic properties in the dehydration and dehydrogenation of ethyl alcohol. It is used in infrared absorbing glass and as a neutron absorber in nuclear reactors.

  • GADOLINIUM

    Harga :

    Minimal Order :

    Gadolinium, particularly in alloy form e.g. Gd5(Si2Ge2), demonstrates a magnetocaloric effect whereby its temperature increases when it enters a magnetic field and decreases when it leaves the magnetic field.

  • THULIUM

    Harga :

    Minimal Order :

    Because of the relatively high price of the metal, thulium has not yet found many practical applications. 169Tm bombarded in a nuclear reactor can be used as a radiation source in portable X-ray equipment. 171Tm is potentially useful as an energy source. Natural thulium also has possible use in ferrites (ceramic magnetic materials) used in microwave equipment, and can be used for doping fiber lasers. As with other lanthanides, thulium has a low-to-moderate acute toxic rating. It should be handled with care.

  • TERBIUM

    Harga :

    Minimal Order :

    Terbium helps enable energy efficient fluorescent lamps, and Terbium metal alloys help to provide suitable metallic films for magneto-optic recording of data. Sodium terbium borate is used in solid-state devices. It can be used with ZrO2 as a crystal stabilizer of fuel cells which operate at elevated temperature.
