Inductive Plasma

Inductive Plasma or inductively coupled plasma as it is often referred to as, is a type of plasma treatment that relies on the use of electromagnetic induction to create extremely high temperature plasma discharges.  Inductive plasma is created usually with argon gas. The gas is fed into a quartz cylinder where a magnetic field exists that is created by an electrode coil wrapped around the cylinder. This induces electric currents within the gas which causes the creation of plasma. The  inductive plasma that is generated can reach temperatures from 6,000 to 10,000 Kelvin (also can be done at much lower temperatures) and is expelled from the cylinder creating an  inductive plasma torch.

The Application of Inductive Plasma

Inductive plasma technology is often utilized in fields such as Powder Spheroidisation and Nano-materials Synthesis. Powder Spheroidisation is a process that is used to change the particle shape of powders in order to improve powder flow, increase packing density and remove internal cavities.  Inductive plasma performs this melting of the rough edged particles in the extreme heat that it generates and then the liquid form of the substance beads up into spheres because of surface tension. The particles stay in the sphere shape once they have cooled down after the  inductive plasma treatment.
