Descrizione del gas
Helium, a rare gas element, is named after the Greek word. The word "helio" represents the sun god in Greek, and when it is associated with the suffix "- ium", it becomes one of the indispensable rare strategic materials for the development of our national defense, military industry, and high-tech industry - helium.
Helium gas has a content of only about 5.2 parts per million in the atmosphere and is usually extracted from natural gas. There are only a few places in the world with a high proportion of helium available for extraction, mainly located in the United States, Poland, Algeria, and Russia. Due to its high value, helium is the only industrial gas in international trade.
Applicazione del prodotto
Helium is usually a colorless and odorless gas, and is the only substance that cannot solidify at standard atmospheric pressure. Helium is the least active element. The application of helium is mainly as a protective gas, working fluid for air-cooled nuclear reactors, and ultra-low temperature refrigerant. Although helium is a rare gas, its applications are extremely extensive, and it plays a very important role in fields such as military industry, scientific research, petrochemicals, refrigeration, medical treatment, and semiconductors.
