摘要：

BkF3 has been found to exhibit a low-temperature, YF3-type orthorhombic structure and a high-temperature, LaF3-type trigonal structure. The lattice parameters of these two BkF3 modifications are: a0 = 6·70±0·01 A, b0 = 7·09·0·01 A, c0 = 4·41±0·01A (orthorhombic), and a0 = 6·97±0·01 A, c0 = 7·14±0·01 A (trigonal), where the error limits reflect the uncertainties in the derivation of the lattice parameters. The inversion temperature of BkF3 lies in the range 350 to 600°C. © 1968.
