radium chloride Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Radium chloride, RaCl2, was the first radium compound to be prepared in a pure state and was the basis of Marie Curie’s original separation of radium from Barium. The first preparation of radium metal was by the electrolysis of a solution of radium chloride using a mercury cathode. The structure remains unknown. Radium chloride is soluble and crystallizes from solution as the dihydrate.
  RaCl2 is used to produce radon gas that in turn is used as a cancer treatment in medicine. This compound is not offered for sale to the general public.

• Chemische Eigenschaften

  radium chloride is yellowish-white crystals becoming yel- low or pink on standing. Radiactive. Soluble in water and alcohol.

• Physikalische Eigenschaften

  radium chloride is a white solid having a blue-green luminescence, especially when heated. It is less soluble in water than other alkaline earth chlorides, a fact which is used in the first stages of the separation of radium from barium by fractional crystallization. It is only sparingly soluble in azeotropic HCl (20.2% HCl) and virtually insoluble in concentrated hydrochloric acid.

• Verwenden

  Radium chloride (RaCl2) has the same use as radium bromide.

• Verwenden

  In physical research. In radiography of metals because the penetration of gamma rays is more pronounced than that of x-rays. As source of radon. No longer used to make luminous paints.

• Hazard

  As for radium.
