摘要：

In a study of the deoxidation equilibria of beta-Ti, beta-Zr and niobium using calcium, solid samples of titanium, zirconium or niobium were equilibrated with liquid calcium in a CaO crucible at temperatures ranging from 1323 to 1723 K. After equilibration the oxygen contents of titanium, zirconium and niobium were analysed. Values for the standard Gibbs energies were determined and the deoxidation behaviour of these refractory metals by calcium is discussed.
