Abstract: Data on growth rates of lithium formate monohydrate (LFM) are determined in-situ at 312.16K.Following Bennema's modification of the BCF surface diffusion model as applied to crystal growth from solution,the values of growth parameters have been calculated and discussed.The results show that the screw dislocation growth is fitted to the growth rate data of (021) and (110) faces of LFM crystals.
