WHAT ARE YOU LOOKING FOR?
Rare earth elements are the Lanthanide elements in the periodic table of chemical elements, including lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium oxide (Nd), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), Ytterbium(III) oxide (Yb), lutetium (Lu), yttrium (Y) and scandium (Sc). A total of 17 elements are called rare earth elements.
Rare earth elements have been widely used in fields such as electronics, petrochemicals, metallurgy, machinery, energy, light industry, environmental protection, agriculture, etc. Rare earth can be used to produce fluorescent materials, rare earth metal hydride battery materials, Electric light materials, permanent magnetic materials, hydrogen storage materials, catalytic materials, precision ceramic materials, laser materials, superconducting materials, magnetostrictive materials, magneto-optical storage materials, optical fiber materials, etc.
The production method of Ytterbium(III) Oxide is mainly oxalic acid precipitation, that is, taking ytterbium chloride or Ytterbium(III) Nitrate solution as raw material, adjusting the Ph value to 2 with oxalic acid, adding ammonia to precipitate ytterbium oxalate, heating, curing, separation, washing, drying at 110 ℃, and then burning at 900~1000 ℃ to form Ytterbium(III) oxide.
