     Information  @ a Glance    

• Helium (He) is a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element.
• Helium is the least reactive noble gas, and thus also the least reactive of all elements; it is inert and monatomic in virtually all conditions.
• Helium is the second lightest element and is the second most abundant in the observable Universe.
• Most helium was formed during the Big Bang, but new helium is being created as a result of the nuclear fusion of hydrogen in stars.

Process

• Crude helium is obtained from the Earth's crust in the course of pumping out natural gas.
• But it's not found in every natural gas deposit, only those where the radioactive decay of nearby uranium has produced helium.
• In the United States, it's obtained mainly from natural gas deposits.

Market

• Helium is a product whose market has continued to undergo rapid change from both a demand and supply perspective.
• Currently natural gas is the only economic source of helium supply.
• Many high technology industries have been developing new commercial applications, which depend on the unique physical properties of helium.
• Leading to ever-increasing helium consumption and potentially accelerating the depletion of finite terrestrial helium resources.

Application

• It is used in filling party balloons as it is a much safer gas.
• It is widely used as an inert gas shield for arc welding.
• It is used to high speed push gas inside air to air missiles for guidence corrections.
• It is a protective gas in growing silicon and germanium crystals, and in titanium and zirconium production.
