Alloys with gallium, antimony and zinc, whose elements, metal constituent WEEE (they are specified for mobile phones) are particularly important for developing photoelectron devices, simple reproductive methods of producing p-n structures GaSb, also for production and construction of photo-wave cells in solar panels and they are also processes which develop ceramic semiconductors. In addition, these alloys represent possible substitute for standard lead-tin seam. For the complete definition of the properties of the ternary Ga-Sb-Zn system there were performed many researches of the alloys. The microstructures of the alloys were investigated by usage of SEM with EDS and optic microscopy. By usage of CALPHAD method there was detected the isothermal cross-section at 25ºC. The GaSb has similarities in the properties and behaviour with GaAs, and it is a potential material for the construction of the p-n diode, the photo-wave and thermo-photo-wave cells in solar panels and LCDs. Newly developed materials have been recommended as an adequate replacement for lead and arsenic, which are very dangerous and harmful metals.

Stopy zawierające gal, antymon i cynk, będące metalicznymi składnikami e-odpadów (są wykorzystywane zwłaszcza w telefonach komórkowych), są szczególnie ważne w budowie urządzeń fotoelektrycznych, w wytwarzaniu struktur p-n GaSb, także w produkcji ogniw fotowoltaicznych i w wytwarzaniu półprzewodników ceramicznych. Ponadto stopy te mogą zastąpić standardowe stopy ołowiowo-cynowe. Dla pełnego określenia właściwości trójskładnikowego układu Ga-Sb-Zn badania stopów przeprowadzono w wielu powtórzeniach. Mikrostruktury stopów badano z wykorzystaniem SEM z EDS i mikroskopii optycznej. Dzięki wykorzystaniu metody CALPHAD stworzono diagram fazowy dla temperatury 25ºC. GaSb wykazuje podobne właściwości i zachowanie do GaAs, a to stwarza możliwość wykorzystania tego stopu do budowy diod p-n, elementów fotoelektrycznych i termofotoelektrycznych, wykorzystywanych w panelach słonecznych i LCD. Nowo opracowane materiały są zalecane jako odpowiednie zamienniki ołowiu i arsenu, które są metalami bardzo niebezpiecznymi i szkodliwymi.
