Magnesium Tellurite

Magnesium Tellurite Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Magnesium tellurite has the molecular formula of MgTeO3 and the molecular weight of 199.9032 g/mol. It can be formed by the solid-state reaction:
  MgO+ TeO2+ heat ? MgTeO3
  An inert atmosphere is required. This salt is a metatellurite. If a solution method is used, the result is likely to be quite different in that a hydrate is formed:
  MgCl2+ Na2TeO3 ? MgTeO3

• Physikalische Eigenschaften

  Additionally, this compound can be prepared by reacting telluriumdichloride in a solution of magnesium chloride:
  MgCl2+ 2TeCl2+ 3H2O ? Te+ MgTeO3+ 6HCl
  In all cases involving solution chemistry, the product is either a pentahydrate or hexahydrate, MgTeO3·5H2O or MgTeO3·6H2O.
  The molecular weights of these compounds are 289.9799 g/mol and 307.9952 g/mol, respectively. If the hexahydrate is heated, a loss of water of hydration occurs at about 105°C.
