摘要：
The quasibinary system Ga2Te3/Ga2Se3 was investigated by X-ray phase analysis and by DTA. The system forms extended regions of solid solutions. The phase diagram can be modelled by a Gibbs energy function for a subregular system with ordering tendencies. From the excess Gibbs energy function the thermodynamic factor for interdiffusion can be calculated. (C) 2004 Elsevier B.V. All rights reserved.
