Magnetic properties of thermal plasma synthesized nanocrystalline nickel ferrite (NiFe2O4)

“…Large scale synthesis of nanomaterials of varieties of metals, metal oxides and nitrides using thermal arc plasma assisted gas phase synthesis, has gained importance in the recent years [5].…”

Al nanoparticles: Impact of media and current on the arc fabrication

“…This method does not require costly equipment in its setup, leading to remarkably lower investment costs compared with the other well-known methods. Moreover, it is very simple and offers the advantage of fabricating various nanostructures by varying the system configuration and deposition parameters [25][26][27]. The plasma evaporator may be scaled up over a broad range of powers by increasing the current (100-2000 A) [25].…”

“…Moreover, it is very simple and offers the advantage of fabricating various nanostructures by varying the system configuration and deposition parameters [25][26][27]. The plasma evaporator may be scaled up over a broad range of powers by increasing the current (100-2000 A) [25]. Many researchers have employed the arc discharge method [25][26][27][28], yet no report has appeared addressing the current and media effect on Al Nps arc discharge synthesis.…”

Preparation of Nano Aluminium Powder (NAP) using a Thermal Plasma: Process Development and Characterization

“…The SEM images show spherical particles, however it was observed that with an increase in H 2 concentration, the particle size was increased. This is attributed to the difference in vaporization rate due to the hydrogen addition in the arc, leading to a higher vapour concentration and resulting in larger diameters of the nanoparticles [42,43] The 2D AFM images (Figure 6) of the NAP prepared under different plasma compositions also confirm the increase in the particle size. However, the particles are < 200 nm at 20% H 2 dilution.…”
