Abstract
The formation of carnallite type double salts by grinding mixtures of hydrated magnesium halide and alkali halides with the same anions was investigated by X-ray diffraction, infrared spectroscopy and thermal a nalysis. Carnallite (KMgCl3. 6H(2)O), cesium-carnallite (CsMgCl3. 6H(2 )O), bromo-carnallite (KMgBr3. 6H(2)O) and cesium-bromo-camallite (CsM gBr3. 6H(2)O) were formed by grinding mixtures of MgCl2. 6H(2)O with K Cl or CsCl and MgBr2. 6H(2)O with KBr or CsBr, respectively. Hydrated solid solutions of magnesium in potassium or cesium halides were obtai ned from that portion of potassium and cesium halides which did not ta ke parr in the formation of the double salt.
