Miscibility study in the bismuth-zinc system extension to the isotherms 425 and 500°C of the ternary system BiSbZn

The 450 °C Isothermal Section of the Zn-Bi-Ni System

“…Researchers have studied the Bi-Zn system through different methods. [14][15][16][17][18][19][20] The phase diagram is uncommon because the miscibility gap is flat and asymmetric. The experiential data concerning the miscibility gap show large variation.…”

Experimental Investigation of the Bi-Sb-Zn System: Study of the Isoplethic Sections Bi-SbZn, Bi-Sb3Zn4 and Bi-Sb2Zn3

“…At 425°C, the onephase liquid field is much reduced, but at 500°C, a liquid solution can be obtained whatever the ratio of bismuth/zinc in the alloy. [3] For the ternary Bi-Sb-Zn system, only one study of the section Bi-Sb 2 Zn 3 was found in the bibliography. According to the authors this would be a quasi-binary isopleth.…”

“…A thermodynamical equation of miscibility curve has been established and the critical point co-ordinates have been calculated: T c = 595°C and x = 0.363. [3] The Sb-Zn system is very complex; it has been the subject of several studies. [5,6] It is mainly characterized by the presence of three intermediate compounds SbZn, Sb 3 Zn 4 and Sb 2 Zn 3 .…”

“…The study of the demixing curve was added by isothermal solubility measurements. [3] A thermodynamic calculation was also undertaken on this system. [4] The Bi-Zn system shows a miscibility gap with a monotectic transformation at 416.8°C: L(x = 0.881) + Zn M L(x = 0.03) and a eutectic transformation at 256°C: Bi + Zn M L(x i = 0.975).…”

Study of electrical conductivity and hardness of the alloys of ternary Bi–Sb–Zn system and calculation of isothermal section at 298 K

“…Given that the Bi-Sb-Zn ternary system is considered as one of the alternative lead-free systems and that zinc alloys, mainly bismuth and antimony doped, are precursors of semiconductors ceramics, it has been widely studied. Majority of papers found in literature are thermodynamic studies and studies of miscibility gap of binary Bi-Sb [1,2], Bi-Zn and Sb-Zn [3,4] systems as well as ternary Bi-Sb-Zn system [5,6]. In our previous work [7] we experimentally and analytically investigated phase diagram of the ternary Bi-Sb-Zn system and three vertical sections of the Bi-Sb-Zn ternary system with molar ratios Bi : Sb = 1, Bi : Zn = 1 and Sb : Zn = 1.…”
