Abstract
The reaction of CaCO3 with NH4Cl leads to formation of CaCl2. In this react ion an intermediate phase is formed, that is be characterized as NH4CaCl3. This intermediate phase crystallizes in the GdFeO3 type and decomposes at e levated temperatures to yield CaCl2 and NH4Cl. The formation and the decomp osition of this intermediate phase as well as the formation of CaCl2 were s tudied with X-ray and thermoanalytical methods.
