Plasma types

Plasma types refer to the different classifications or states of plasma, which is one of the four fundamental states of matter, alongside solid, liquid, and gas. Plasma is formed when a gas is energized to the point that ionization occurs, meaning that electrons are stripped from atoms, resulting in a collection of charged particles: ions and free electrons. This gives plasma unique properties, including electrical conductivity, responsiveness to magnetic fields, and the ability to emit light.

Terrestrial plasmas refer to plasma phenomena that occur in the Earth's atmosphere and near-Earth environment. Plasma, often referred to as the fourth state of matter, is created when gases are energized to the point that electrons are stripped from atoms, resulting in a collection of charged particles, including ions and free electrons.

Fire is a chemical reaction that results from the rapid oxidation of a material, typically involving the combination of oxygen with a fuel in the presence of heat. The reaction produces heat, light, and various reaction products, mainly gases such as carbon dioxide and water vapor. Fire is often characterized by flames, which are visible manifestations of the reaction, and it can produce heat and light.

Atmospheric-pressure plasma refers to a state of matter created when a gas (usually at or near atmospheric pressure) is ionized, resulting in a mixture of ions, electrons, neutral particles, and excited species. Plasma is often called the fourth state of matter, alongside solid, liquid, and gas.

Capacitively Coupled Plasma (CCP) refers to a method of generating plasma using an RF (radio frequency) electric field. This technique is commonly used in various applications such as semiconductor manufacturing, surface treatment, and material processing.

Induction plasma refers to a form of plasma generation that utilizes inductive coupling to create and sustain a plasma state. This method typically involves the use of an induction coil, which creates an oscillating magnetic field. When a gas (such as air, argon, or helium) is introduced into the area where the induction coil operates, the rapidly changing magnetic field induces electric currents within the gas, leading to ionization.

Microplasma refers to a type of plasma that is generated and maintained at a much smaller scale compared to conventional plasmas. Plasmas are ionized gases consisting of charged particles (ions and electrons) and neutral atoms or molecules. Microplasma, in contrast, typically operates at low power levels and can be generated under atmospheric or near-atmospheric conditions.

Non-neutral plasma refers to a type of plasma that has an imbalance in the number of positive ions and negative electrons, leading to a net electric charge. In contrast, a neutral plasma typically contains equal amounts of positive and negative charges, which results in a net charge of zero. In non-neutral plasmas, the excess of one type of charge can create electric fields and potential gradients that affect the dynamics and behavior of the plasma.
