Applications of Inert Gases. There are numerous uses of inert gases or noble gases in various fields specially in the field of metallurgy. Here we are listing few applications of each inert gas separately in many fields –. Helium. Helium is used for the treatment of asthma, emphysema and other breathing problems. Helium is used in balloons.
Ion Beam Etch and Milling is a dry plasma etch method which utilizes a remote broad beam ion/plasma source to remove substrate material by physical inert gas/or chemical reactive gas means. Ion Milling is used where traditional plasma etch fails or is difficult such as resistant materials, new materials, or very thin layers or multi-layers.

Optimized in three decades of NOLL's practical experience: processing in an inert protective medium. Under nitrogen or – for special materials and refinement – under argon. We've set highest safety standards to prevent the risk of inflammation, explosion and fire. Depending on product and processing technique, the oxygen range in the protective atmosphere is maximally […]
Ion milling is a process by which inert gas ions from a broad beam ion source are accelerated towards the surface of a substrate to effect physical etching. The ion milling or sputtering is a physical process and does not have any chemical componet as opposed …
Elaborate technical solutions such as systems for dust removal and inert gas overlay are often necessary to achieve the required level of safety. The cost for these filtration machines often significantly exceeds that of the actual mill.
Dilution takes place when the incoming inert gas mixes with the original tank atmosphere to form a homogeneous mixture throughout the tank so that, as the process continues, the concentration of the original gas decreases progressively. It is important that the incoming inert gas has sufficient entry velocity to penetrate to the bottom of the tank.
The inert gas shielded jet mill is used in metal powder, easily oxidized raw materials, flammable and explosive raw materials, pharmaceutical ultrafine powder and other industries and raw materials that require inert gas protection. Typical materials are: cobalt powder, tungsten powder, iron powder, nickel powder, tantalum powder, selenium powder, fine spherical aluminum powder, …
Typically, the inert gas is fed into the milling chamber via nitrogen ports at the desired pressure and volume. A variety of different components can be used in conjunction with nitrogen ports, such as temperature probes, oxygen analysers, pressure relief (venting) valves, PLC logic controls and pressure regulators; all used to help guarantee a ...
Inert gas: A gas that is not toxic, which does not support human breathing and which reacts little or not at all with other substances. The common inert gases are nitrogen and the rare gases like helium, argon, neon, xenon and krypton. Flammable gas: a gas whose major hazard is flammability. Note that all flammable gases also act as asphyxiants.
2. How does a jet mill work ? The working principle of jet mills is explained in this part. 2.1 High velocity impact The principle of size reduction applied in a jet milling machine is to have high velocity impact, in between the particles, and in between the particles and the milling chamber.A gas (typically air, for air jet mills) injected at high speed provides the energy required for ...
A jet mill grinds materials by using a high speed jet of compressed air or inert gas to impact particles into each other. Jet mills can be designed to output particles below a certain size, while continue milling particles above that size, resulting in a narrow size distribution of the resulting product.
Ion Milling is a physical etching technique whereby the ions of an inert gas (typically Ar) are accelerated from a wide beam ion source into the surface of a substrate (or coated substrate) in vacuum in order to remove material to some desired depth or underlayer. It is easily visualized as "atomic sandblasting", or more accurately "ionic ...
