MASS SPECTROMETRIC STUDY OF THE VAPORIZATION OF THE TI-B SYSTEM

Abstract

A mass spectrometer was used with Knudsen cells to study the vaporization of the titanium-boron system. The pressures of Ti(g) and B(g) were determined over several condensed phases and yielded values of 430 kcal/mole and -52 kcal/mole or the heats of vaporization and formation of TiB2, respectively. Thermodynamic functions for TiB(s) were obtained.
