The enthalpy of a sample of lithium tetrafluoroberyllate, LiBeF, of 98.6 percent purity was measured relative to 273 K at eleven temperatures from 323 to 873 K. Corrections were applied for the impurities and for extensive premelting below the melting point (745 K). The enthalpy and heat capacity, and the entropy and Gibbs free-energy function relative to the undetermined value of were computed from empirical functions of temperature derived from the data, and are tabulated from 273 to 900 K.
对纯度为98.6%的四氟铍酸锂（LiBeF）样品，在323至873K的11个温度下，相对于273K测量了其焓。对杂质以及低于熔点（745K）时的大量预熔进行了校正。根据从数据得出的温度经验函数，计算了相对于未确定值 的焓和热容，以及熵和吉布斯自由能函数，并列出了273至900K范围内的数据。
