The Floatation Process Of Rare Earth

  • OSA | The mechanism of rare earth incorporation

    The mechanism involved during solution doping process has been systematically investigated by correlating the soot characteristics and solution parameters with the amount of rare earth (RE) incorporated in the core of optical fiber. Experiments show that the amount of RE incorporation may be controlled with better precision by adjusting Al ion concentration in the soaking solution.

    The individual rare-earth R 3+ complexes form rectangular bands with a minimum overlap of adjacent bands. The given rare-earth solution is collected, and the R 3+ ion is precipitated out of solution using oxalic acid. The rare-earth oxalate is converted to the oxide by heating it in air at 800–1,000 °C (1,472–1,832 °F).
