Abstract
A method for preparation of high- purity molybdenum trioxide by desublimating its vapors from oxygen flow is proposed. X- ray diffraction analysis confirmed the formation of rhombic molybdenum trioxide (Pmna, a = 13.7690(4)Å b = 3.70318(10)Å c = 3.95972(10)Å Z = 4). Iodometric titration has shown that the resulting product possesses an increased content of oxygen atoms compared to stoichiometric one and corresponds to the MoO formula. The content of metallic elements impurities at the 1 - 10 ppm level was found by laser mass spectrometry. The low content of transition element impurities and the excess of oxygen atoms over the stoichiometric MoO composition make us hopeful that the use of molybdenum trioxide deposited from the oxygen flow allows us to prepare glasses with high optical transparency.
