Thermochemical properties of SrBO2(g) and SrB2O4(s)

Thermodynamic properties and structure of gaseous metaborates

“…At present, a considerable number of works [53][54][55][56][57][58][59][60][61][62][63] (predominantly performed using high-temperature mass spectrometry) have been devoted to investigation of the vaporization in MO-B 2 O 3 systems (where M is an alkaline-earth ions are equal to 8.4 and 12.0 eV, respectively. Furthermore, the ionization efficiency curve for MgB ions exhibited a kink, which was assigned to dissociative ionization of MgB 2 ions.…”

“…The calculated standard enthalpies of formation of gaseous BaBO 2 and BaB 2 O 4 at 0 K are equal to -675.3 ± 29.3 and -1344 ± 44.8 kJ/mol, respectively. In a series of works [56][57][58][59][60], the authors studied the vaporization processes in the SrO-B 2 MBO 2 were calculated from the equilibrium constants experimentally obtained in the range 1390-1535 K. These enthalpies are equal to -636 ± 19 kJ/mol for SrBO 2 and -633 ± 21 kJ/mol for BaBO 2 . Moreover, the enthalpy of formation of gaseous CaBO 2 was estimated at -526 ± 46 kJ/mol in [58].…”

Ion chemistry and ionic thin film deposition from HMDS‐photochemistry induced by VUV‐radiation from an atmospheric plasma

“…As both of these species are expected to be from the plasma region, either of them could be ionized. In case of the argon plasma photons, downstream ionization of $${{\rm{B}}}_{2}{{\rm{O}}}_{3}$$ by the radiation is not possible (ionization potential 13.3 eV [ 88 ] ), which explains the lower relative abundance of the ion at 171 amu when compared with the abundance with helium plasma photons. A similar explanation for the formation of the species at 100 and 101 amu as well as 200 amu is unfortunately not possible.…”
