摘要	The enthalpies of solution of (NH4)(2)B4O7.4H(2)O (cr) and NH4B5O8.4H(2)O (cr) in approximately 1 mol dm(-3) aqueous hydrochloric acid solution, as well as the enthalpy of solution of NH4Cl (cr) in aqueous (hydrochloric acid + boric acid) have been measured by using a microcalorimeter. From these results and other auxiliary data, the standard molar enthalpies of formation Delta(f)H(m)(0) of (NH4)(2)B4O7.4H(2)O (cr) and NH4B5O8.4H(2)O (cr) have been derived to be (-4313.74 +/- 3.26) and (-4703.56 +/- 4.03) kJ mol(-1) at 298.15 K, respectively. Some other thermodynamic properties of the title borates, such as the standard molar entropies of formation and the standard molar entropies have also been calculated.
