In physics and chemistry, plasma (also called an ionised gas) is an energetic gas-phase state of matter, often referred to as "the fourth state of matter", in which some or all of the electrons in the outer atomic orbitals have become separated from the atom or molecule.
Plasma physics is important in astrophysics in that many astronomical objects including stars, accretion disks, nebula, and the interstellar medium consist of plasma.
The dynamics of plasmas interacting with external and self-generated magnetic fields are studied in the academic discipline of magnetohydrodynamics.

The plasma medium is inherently nonlinear because the charged particles composing the plasma interact collectively with the electromagnetic fields produced self-consistently by the charge density and currents associated with the plasma particles.
A recent National Research Council report[1], which highlights the importance of plasma processing in the electronics industry, indicates that the worldwide sale of plasma reactors alone amounted to $1 billion dollars in 1990 and is expected to double in the next five years.
Examples of applications of nonneutral plasmas are electron beams and plasmas for the generation of electromagnetic waves, pure ion plasmas in traps for atomic clock applications, advanced concepts for particle accelerators, and the confinement of antimatter such as positrons and antiprotons.

Plasma science is the study of the nonlinear collective interactions of electrically charged particles with each other, with neutral atoms and molecules, and with electric and magnetic fields.
Thermal plasma processing applications range from physical transformation of materials such as bulk melting in metallurgical plasma furnaces, metal cutting and welding, or powder melting during spraying, to driving chemical reactions, as in the reduction of oxides, in the synthesis of ceramic powders or films, or in the destruction of hazardous chemical wastes.

 Vacuum Plasma Processing
Because plasmas affect materials at an atomic level, it is often necessary to use surface analysis techniques such as scanning electron microscopy and X-ray photoelectron spectroscopy to identify the processes required and to judge their effects.
The plasma energy is highly efficient because the vacuum pressure reduces recombinations, and increases the mean free path length of the particles resulting in higher ionic kinetic energies.
Plasma technology has many advantages thermodynamically unfavourable reactions can be achieved at low temperatures, surfaces can be cleaned with no residues, and it eliminates the need to use primers and pretreatments for adhesion promotion.
