(2) Flash joule synthesis of high entropy alloy

The high entropy alloy was synthesized by flash joule heat technique. This technique involves mixing a moderate amount of a carbon source, (such as activated carbon or carbon black), with a metal salt precursor at high temperatures. At temperatures in excess of 2000 K, the combustion of the carbon source produces a thermal shock that rapidly reduces the metal salt to metal atoms, then form a solid solution structure at high temperatures and produce a high-entropy alloy by rapid cooling (105 K·s−1).

This method can achieve rapid diffusion and uniform distribution of metal atoms in a short time, so as to form an alloy with uniform composition.By adjusting the type and amount of carbon sources, the microstructure and properties of the alloy can be adjusted.

(3)Extraction of heavy metals from coal ash by flash joule heating technology

Removal of heavy metals from coal fly ash by flash Joule heating (FJH) technology. The technology is able to raise the temperature to about 3000°C in a short time, achieving efficient removal of heavy metals such as arsenic, cadmium, cobalt, nickel and lead with a removal rate of 70-90%.

Treated coal fly ash (CFA) can be used as an alternative to Portland cement, improving the strength of the cement, reducing heavy metal leakage in acidic environments. In addition, the technology performs well in terms of energy efficiency and cost effectiveness, electricity costing about $21 per ton. Life cycle analysis shows that the reuse of CFA helps to reduce greenhouse gas emissions and heavy metal emissions, energy consumption is effectively balanced compared to landfill. FJH technology is not only suitable for the treatment of coal fly ash, but also has potential for other industrial waste decontamination treatment.
