Cold Plasma Breakthrough

After many years of pioneering research, ILTONG’s Scientists have now successfully developed and patented world first cold plasma technology in such a way as to sustain cold plasma indefinitely, utilizing large areas of plasma in a small unit that is 4 times more economical to run. This gives the same fantastic effects that plasma is known for with an almost unlimited number of cost effective industrial applications.

The ILTONG Group has now established itself as the world leader in cold (non-thermal) plasma technologies, with recent breakthroughs new and exciting applications are now being designed that will make a significant impact on our health and the environment.

Plasma is by far the most common phase of matter in the universe, both by mass and by volume. All stars are made of plasma and even the space between the stars is filled with plasma, albeit a very sparse one. In our solar system, The sun and almost all stars are almost entirely plasma (i.e., over 99%) both by mass and by volume. This plasma consists mainly of electrons and protons (which would form hydrogen gas if the particles recombined), and also some heavier ions derived from other elements that have lost one or more of their electrons.

We are familiar with the states of matter that include solids, liquids and gases. Plasma, which is the so-called "fourth state of matter" as we know them, exists when energy levels are so high that electrons are driven from their orbitals in the extremes of the temperatures. On earth, we encounter plasma in lightning, and also in a few other situations where temperatures are extremely high.

Very small grains within a gaseous plasma will also pick up a negative charge so that they in turn may act like a very heavy negative ion component of the plasma. Plasma temperature is commonly measured in kelvins or electron volts and is, informally, a measure of the thermal kinetic energy per particle. Very high temperatures are usually needed to sustain ionization, which is a defining feature of plasma. The degree of plasma ionization is determined by the “electron temperature” relative to the ionization energy in a relationship called the Saha Equation. At low temperatures, ions and electrons tend to recombine into bound states – atoms, and the plasma will eventually become a gas.

In most cases the electrons are close enough to thermal equilibrium that their temperature is relatively well defined, even when there is a significant deviation from the Maxwell-Boltzmann energy distribution function, for example, due to UV radiation, energetic particles or strong electric fields. Because of the large difference in mass, the electrons come to thermodynamic equilibrium amongst themselves much faster than they come into equilibrium with the ions or neutral atoms. For this reason, the “ion temperature” may be very different from the “electron temperature”. This is especially common in weakly ionized technological plasmas, where the ions are often near the ambient temperature.

Based on the relative temperatures of the electrons, ions and neutrals, plasmas are classified as “thermal” or “non-thermal”. Thermal plasmas have electrons and the heavy particles at the same temperature, i.e. they are in thermal equilibrium with each other.
 
Non-thermal plasmas on the other hand have the ions and neutrals at a much lower temperature (normally room temperature), whereas the electrons are much hotter.
A plasma is sometimes referred to as being “hot” if it is nearly fully ionized, or “cold” if only a small fraction (for example 1%) of the gas molecules are ionized, but other definitions of the terms “hot plasma” and “cold plasma” are common. Even in a “cold” plasma, the electron temperature is still typically several thousand degrees Celsius. Plasmas utilized in “plasma technology” (technological plasmas) are usually cold in this sense.
