Sol–Gel Autocombustion Synthesis of Metals and Metal Alloys

Abstract

Go for the burn! Sol–gel autocombustion is an energy-efficient approach to synthesizing metals, such as Co, Ni, Cu, Ag, Bi, and Co–Ni alloy. Based on differential thermal analysis (DTA) and mass spectrometry measurements (see picture for Ni gel), a reaction mechanism is proposed that leads to the formation of metals and metal alloys instead of metal oxides.
