Rare Earth Oxides Cas No 12055-62-8 Holimium Oxide 99.9 % 99.999 % for Special catalyst

It is used to make the new type of light source dysprosium holmium lamp, and can also be used as the additive of yttrium aluminium garnet and the preparation of metal holmium.
Holmium oxide can be used as a yellow and red colorant for the Soviet diamond and glass.The glass and holmium oxide solution of holmium oxide (often perchlorate solution) in 200-900 - nm range of spectral absorption peak Octavia, thus can be used as a spectrometer calibration standards, and has been commercialized.Like other rare earth elements, holmium oxide is used as a special catalyst, phosphor and laser material.
