Lithium is found to transform from a body-centered cubic (bcc) to a face-centered cubic (fcc) structure at 6.9 gigapascals (69 kilobars) and 296 kelvin. The relative volume of the bcc structured lithium at 6.9 gigapascals is 0.718, and the fcc structure is 0.25 percent denser. The bulk modulus and its pressure derivative for the bcc structure are 11.57 gigapascals and 3.4, and for the fcc structure are 13.1 gigapascals and 2.8. Extrapolation of the bcc-fcc phase boundary and the melting curve indicate a triple point around 15 gigapascals and 500 kelvin.
锂在 69 吉帕斯卡（690 千巴）和 296 开尔文时被发现从体心立方（bcc）转变为面心立方（fcc）结构。6.9 吉帕斯卡时 bcc 结构锂的相对体积为 0.718，fcc 结构的密度增加了 0.25%。bcc 结构的体弹模量及其压力导数为 11.57 吉帕斯卡和 3.4，fcc 结构的体弹模量及其压力导数为 13.1 吉帕斯卡和 2.8。bcc-fcc 相边界和熔化曲线的外推表明，在约 15 吉帕斯卡和 500 开尔文附近存在一个三相点。
