The work presents emission factors of main air pollutants for installations of ArcelorMittal Poland S.A. Unit in Krakow (Poland) in comparison with analogous characteristic emissions for iron and steel industry in West Europe. In the comparison four installations (to coke, sinter, pig iron and steel production) were taken into consideration. The emission rates from ArcelorMittal Poland S.A. Unit in Krakow were estimated on the basis of the emission levels and production data from 2004, when took place the most significant production of liquid steel during last several years. As a result of the analysis, most the emission factors (with the …

The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and microhardness investigations were used in order to determine structural characteristics of chosen Ag-In-Sn ternary alloys.
