A new force field (MSXX FF) was developed for barium sulfate (BaSO_4) to reproduce the experimental properties of BaSO_4 crystal (density, lattice energy, compressibility, and vibrational spectrum) and to describe properly the interaction between BaSO_4 and water (binding energies and interatomic distances of Ba(H_2O)_8^(2+) and (SO_4)(H_2O)_6^(2-) clusters determined from ab initio quantum mechanics calculations). Using this FF in combination with F3C FF for water, the surface energies for several surfaces of BaSO_4 were examined both in a vacuum and in the presence of an explicit water bath in contact with them. The same level of FF's are also reported for CaSO_4 and SrSO_4.
