摘要：

Vaporization in the SrO-B//2O//3 system has been studied by a mass spectrometric Knudsen effusion method in the temperature range of 1281-1572 K. The vapor species Sr(g), SrBO//2(g), BO(g), B//2O//2(g), and B//2O//3(g) have been identified. On the basis of the partial pressures, the enthalpy of formation and the dissociation energy for SrBO//2(g) have been determined and are compared with the values obtained for other alkaline earth metaborates and oxides and further alkali metaborates and monoxides.
