Popis:	The solubility of cobalt in α thorium is described by the equation c s (at.% Co) = 10970 exp(−13844/ T ). The heat of solution is −115.2 kJ mol − Co and the terminal solubility at the eutectic temperature 1100 °C is 0.46 at.% Co. A newly identified metastable phase with a plate morphology is present in thorium-rich alloys on quenching from the high (αTh) region. Upon aging for different times at 500 °C and above, this phase transforms to rod-like particles of Th 7 Co 3 .
