Structural Changes in GaAs Crystalline Compound Caused by Combined Ball Milling and Heat Treatment

X-ray diffraction technique was applied to register structural changes in gallium arsenide (GaAs) crystalline compound induced by combined a high-energy ball-milling and subsequent post-annealing treatments. During milling (up to 10 h) in air at room temperature the GaAs crystals disintegrate into two phases: one crystalline phase identified as an arsenic oxide (As_2O_3) and one amophous phase. During the subsequent annealing (up to 1h) in the temperature range 450-750 ˚ C, the amorphous phase transforms into gallium oxide (Ga_2O_3) phase, while (As_2O_3) evaporates and escapes from the solid milled sample. This study is interesting as a recycling path of GaAs convenient from the ecological aspect.
