A new Al-Si-Ni high-temperature processed alloy has been obtained using sodium fluosilicate as a source of Si and nickel oxide as a source of Ni. Throughout the study, we tested the optimum parameters affecting the preparation of Al-Si-Ni ternary alloy;   bath temperature, Na₂SiF₆/Al_total w.t ratio, Ni₂O₃/Al_total and reaction time. The optimum processing parameters are; temperature 950^oC, Na₂SiF₆/Al_total wt. ratio is 1, Ni₂O₃/Al_total wt. ratio is 0.082 and reaction time is 25 min. Some tests such as chemical analysis, X-ray diffraction and microstructure examination were carried out on the produced alloys. The obtained results indicate that the produced alloys containing up to 10.75% Si and 2.86 Ni in the form of Al₃Ni. The presence of eutectic Si and eutectic Al₃Ni could form interconnected system and it can be used as high-performance alloys at elevated temperature.
