Abstract:One new hydrated barium hexaborate has been prepared and identified by chemical analysis,X-ray diffraction(XRD),infrared spectral(IR)and thermal analysis(TG-DTG,DSC).The constitute of sample is BaB_6O_(10)·4.5H_2O.The structure and thermal decomposition process of sample were studied.The molar enthalpies of solution of BaB_6 O_(10)·4.5H_2 O in 1 mol·dm~(-3) HCl (aq)were measured in a series of experiments.With the incorporation of the previously determined enthalpy of solution of other substances in HCl(aq)and the standard molar enthalpies of formation of related substances,the standard molar enthalpies of
Keywords:barium hexaborate  thermochemistry  standard molar enthalpy of formation
