The Bi-In-Te ternary system is an important thermoelectric material system, but phase diagram encompassing the entire compositional range of this system is missing. To provide fundamental information for thermoelectric and related studies, this study experimentally determines the Bi-In-Te phase diagram,...
1.8 Peritectic phase diagram 随着研究的不断深入,人们对于包晶凝固过程中的形核机理有了进一步的认识。早期的研究者通常认为在包晶合金凝固过程中,初生相与包晶相之间具有较好的晶格匹配性,导致初生相在包晶相的形核中可以起到形核基底的作用。但是,近年来人们也发现了包晶相由液相直接形核,然后再通过初生相的溶解...
In the present article, a re-evaluation of the thermodynamic parameters and phase diagram of the Ce–Te binary system and an initial assessment of the Ce–Te–Bi ternary system have been carried out. The new modelling of the Ce–Te system contains two modifications of the liquid phase and t...

In this context, the precise knowledge of the phase diagram can be a powerful tool to properly control the carrier concentration. The solidus line, characterizing the maximum deviation from stoichiometry, was investigated in the past in the Te and Sb rich-side of the Sb2−xBixTe3 (x = ...
Keywords: binary alloy; phase diagram; X-ray diffraction; superlattice 1. Introduction Compounds in the Sb–Te and Bi–Te systems have been widely used as base materials for optical disks and thermoelectric materials, and many studies have attempted to discern their phase diagrams and crystal ...
The phase relations in the quaternary system Bi/Se/O/Cl have been studied and the existence of several new compounds in the pseudoternary area Bi2O3/Bi2Se3/BiCl3 has been established by solid state and chemical vapour transport reactions. The phase diagram is derived from X-ray...
