Here, we propose a novel process for smelting Sc metal by microwave irradiation. Sc metal was able to be obtained successfully from ScF₃ through a microwave-irradiation-based carbon reduction reaction. The reaction temperature for this reduction process was approximately 880°C, which is half of that for the conventional smelting process ...
Aluminum anodes with fine grain have stronger electrochemical activity and higher corrosion resistance, but the microwave-smelted aluminum alloy anode can be prepared with fine grain. In this work, microwave smelting has been used to refine grain size and optimize the precipitated phase in an aluminum alloy anode. The results show that microwave can not only …

Smelting in a Microwave *He successfully melted tin/silver solder at 392°F/220°C, but could only get silver up to 1,475°F/800°C, short of the 1,964°F/962°C melting point. Quote
Some researchers have also proposed smelting metal using microwave heating in order to achieve a decrease in CO 2 emissions 13,14. In addition, Yoshikawa and Morita have reported the microwave-based carbothermic reduction of MgO, using amorphous carbon instead of ferrosilicon as the reduction agent, which yielded particles of Mg metal so tiny ...
Microwave heating is well-suited for high-temperature processes up to 2000°C and beyond, such as smelting ores for metal extraction and pyrolyzing waste. This is because microwave heating can help accelerate specific chemical and physical changes in materials faster than traditional methods by selectively interacting with polar molecules, and ...
The application of microwave technology in mineral metallurgy is a transformative approach to ore processing that offers new ideas about the current progressive depletion of resources and the environmental impact of mineral processing. This review delves into the principles, applications, and future directions of microwave treatment in mineral and ore …
