基于相隔约20年的两项研究发现，在室温和常压下，双密排六方βCe相缓慢转变为面心立方γCe相。这表明γCe是标准温度和压力下的稳定变质（即，298 K和1 atm）。给出了β Ce和γCe在1atm下的平衡温度、相变热、温度/压力相图和热容。
Based on two studies carried out about 20 years apart, it was found that the double close-packed hexagonal βCe phase slowly transformed to the face-centered cubic γCe phase at room temperature and ambient pressure. This indicates that γCe is the stable modification at standard temperature and pressure (i.e., 298 K and 1 atm). The βCe↔γCe equilibrium temperature at 1 atm, the heat of transformation, the temperature/pressure phase diagram, and the heat capacities of βCe and γCe are presented.
