**2.4 Application of plasma**

In the last two decades, plasma has claimed to be an emerging solution to numerous processes due to its unique features and hence implemented in various sectors [4, 6–10]. Plasma finds significant industrial applications viz. melting, smelting, smelting and reduction, remelting and refining, spark plasma sintering, surface modification, and surface coating.

## **2.5 Advantages of plasma over conventional processes**

Although there are a lot of many advantageous aspects behind the utilization of plasma, some of the important features are given in **Table 1**.
