- Abstract
This work presents data on the experimental study of CaCO stability (3.0-5.5 GPa; 1300-1400°C) under reducing conditions modeling the presence of metallic iron. It is established that CaCO is stable at the above P-T parameters under reducing conditions (in the presence of metallic Ti). CaCO decomposed only when it chemically interacted with iron, forming Ca-ferrites and releasing solid carbon in the form of graphite in the closed system (in sealed Pt-ampoules).
