To accurately predict the crystal morphologies of dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate( HATO,also known as TKX-50) under different growth conditions,the PCFF force field parameters were systematically validated and modified. The attachment energies of HATO crystal surface were calculated by the molecular simulation method. The crystal morphologies of HATO in vacuum,in seven solvents( water,dimethyl sulfoxide,methanol,ethanol,ethyl acetate,tetrahydrofuran and trichloromethane),and in three addit...
