AB  - It is known that virtually all of the nickel in nickel sulfide ores occurs in the
mineral pentlandite [(Ni,Fe)9S8]. Therefore, pentlandite is the most common and
abundant ore for extraction of nickel, accounting for over 60% of nickel world
production [1, 2].
The pyrometallurgical extraction of nickel from its sulfide ores is very similar
to the copper extraction process from copper sulfide concentrates. In essence, iron
and sulfur are eliminated by selective oxidation and fluxing. In fact, the oxidation of
pentlandite is the most important chemical process in the pyrometallurgical route
[3].
Because of all mentioned, the characterization of the structural properties of
six pentlandite samples was carried out in this paper. The samples of pentlandite
were roasted in air atmosphere for 30min, in five different temperatures: 400, 500,
600, 700 and 800 °C. Investigation of structural properties and obtained oxidation
products was performed using X-ray diffraction (XRD), scanning electron microscopy
(SEM) and energy dispersive spectrometry (EDS).

AB  - High toxicity of lead and damaging effects on the environment resulted in its prohibited
use in electronic materials (RoHS Directive from 1 July 2006 in the EU). Therefore, great
effort has been made on the development of new Pb-free soldering and brazing materials
[1-5]. The Bi–Cu–Ni ternary system belongs to the group of potential Cu-Ni-based
advanced lead-free solder materials for high temperature application [6-8]. The results of
phase equilibria investigation of the alloys selected in the Bi-Cu0.75Ni0.25 section from
bismuth corner with molar ratio Cu:Ni = 3:1, are presented in this paper. The investigations
were performed using DTA/DSC experimental methods, while thermodynamic calculation
was done according to the CALPHAD method using PANDAT software. The results of the
DTA/DSC heating measurements of the chosen samples in the Bi-Cu0.75Ni0.25 section,
including liquidus temperatures and other phase transition temperatures are presented in
graphical abstract. The phase diagram of the investigated Bi-CuNi section has been
calculated using PANDAT software and is presented in graphical abstract, together with
experimentally determined DTA/DSC points. It could be noticed that calculated phase
diagram is in good agreement with DTA/DSC experiments.
