Application:
Holmium oxide for the manufacture of the new light source lamp dysprosium, holmium, yttrium iron can be used as yttrium aluminum garnet eligible additives and preparation of metal holmium. For the Soviet diamond and glass yellow, red colorant. Glass and holmium oxide holmium oxide solution containing (usually perchloric acid solution) spectrum in the 200-900nm range has Octavia absorption peak, and therefore can be used as the spectrometer calibration standard, holmium oxide can also be used as special catalyst, phosphor and laser material. Holmium laser wavelength of about 2.08 μm, for medical, optical radar, wind speed measurements and atmospheric monitoring.
