History of Science and Engineering Annotation << Back ON THE HISTORY OF CRYSTALCHEMICAL STUDIES OF MOLYBDENUM AND TUNGSTEN TRIOXIDES A.M. Smolegovskiy Oxygen connections of hexavalent molybdenum and tungsten are major among the oxides of these elements. Both in chronologic and in methodical aspects, and in regard to the deposit of concrete scientists, and also in the plan of general crystalchemistry conception history of their study has many general lines. From convention of their separate consideration is here clear. At the same time besides the comfort of exposition the last proves to be correct the fact of structural distinction of oxides of molybdenum and tungsten. Keywords: oxygen compounds; Trioxide; oxide; molybdenum; tungsten. Contacts: E-mail: smolegovskiy@mail.ru Pp. 43-67.
