Hello Lightning Tamers!
In today’s podcast, I’ll be joined by Ben Orozco for Chapter 3 of the Intro to Plasma series in collaboration with GEEX, the Glass Education Exchange. We’ll be talking define plasma, discuss the mixture of gases and vapors, and get in depth about how to fill a vessel. Beyond the technical: another crucial component of plasma is the chemistry of collaboration. Percy and Ben note the differences between fabrication and collaboration, and offer advice on what to consider when working with the plasma community. |

About | Rare Gas Market
”Things have changed a bit in the rare gas market. The source for crude rare gases are large Air Separation Units (ASU’s). These facilities use refrigeration and pressure to separate air into its various gas components. As the air is chilled, each component drops as a liquid when the temperature drops below its boiling point.
Because of the huge requirement for oxygen at steel plants, the largest ASU’s in the world were constructed at or near the largest steel plants in the world. Those plants are located in China, Russia and Ukraine.
The virus has had a huge impact on the global demand for steel, causing steel plants to reduce production levels. As the production decreased, the operating hours of the3 ASU’s were reduced. This is causing a global shortage of rare gases.
Krypton gas has seen the highest increase. Besides the shortage for crude gas from the ASU’s, several semiconductor manufacturers have significantly increased their requirement for the gas. As the krypton is only a small fraction of the cost profile of these semiconductor fabrication facilities, the cost of the gas is a small consideration to them. They need the gas, so they buy the gas.
At this time, both Airgas / Air Liquide & Linde / Praxair are not quoting new customers on krypton gas and have placed most customers on allocation for the gas.
