my country’s liquid argon (Ar) output ranks among the top in the world, with stainless steel and monocrystalline silicon being its main demand ends.

Liquid argon is liquid argon, with the chemical formula Ar. It is a liquid gas at extremely low temperatures, with a boiling point of -185.9°C. It appears as a colorless gas, odorless and tasteless, slightly soluble in water and soluble in ethanol. Depending on the purity, liquid argon can be divided into high-purity argon and ordinary argon. Argon is the most abundant rare gas in the air. Therefore, liquid argon is mainly prepared through air separation. The specific process is to distill the liquefied air to obtain crude argon, and then purify the crude argon to obtain liquid argon.

Liquid argon plays an important role in semiconductors, medical care, metal smelting, metal welding, industrial production, scientific research and other fields, and has a wide range of applications. Specifically, in the semiconductor field, liquid argon can be used as a protective gas in the production process of high-purity silicon and germanium crystals; in the medical and health care field, liquid argon is mainly used to freeze and preserve biological samples such as human tissue, blood, and organs, and also It can be used to treat lipomas, warts, warts and other diseases; in the field of scientific research, liquid argon is mainly used to cool experimental equipment such as nuclear magnetic resonance machines and electron microscopes; in the field of metal smelting, liquid argon is mainly used in low alloy steel, stainless steel, Heat-resistant steel and other special steel blowing links.

Stainless steel blowing is the main application scenario of liquid argon. my country is a major steel producer. According to data from the China Tegon Association, China’s crude stainless steel production in 2022 will be 31.975 million tons. Domestic stainless steel production is huge, resulting in high demand for liquid argon and good industry development prospects.

According to the “China Liquid Argon (Ar) Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research CenterShows that monocrystalline silicon production is another important application scenario of liquid argon. Monocrystalline silicon is a key material for the production of solar cells. Under the current booming development of the domestic photovoltaic industry, the continued growth of solar cell output has driven the rapid development of the monocrystalline silicon market, which in turn has brought broad demand for the liquid argon market. The domestic monocrystalline silicon market size will exceed 50 billion yuan in 2022. As a result, the domestic liquid argon market size will reach 9.5 billion yuan in 2022.

The main liquid argon production companies in my country include Weiyuan Co., Ltd., Jiangsu Thorpe, Kemet Gas, Hongren Special Gas, Dumaoai Purification Gas, Hangyang Co., Ltd., Baosteel Gas, Yingde Gas, etc. There are a large number of domestic liquid argon companies. As local companies continue to release their production capacity, the liquid argon market is well supplied. At present, our country has become a major producer and exporter of liquid argon in the world.

Industry analysts said that from the perspective of the global liquid argon market, Chinese companies still occupy a relatively small share, and the market is still dominated by German Lin Internationally leading special gas companies such as Deutsche Gas, Germany’s Messer, France’s Air Liquide, the United States’ Praxair, and the United States’ Air Chemicals dominate the market. In the future, domestic liquid argon companies will need to continuously improve their technical level and increase their high-purity argon supply capabilities to improve the competitiveness of local companies in the global market.
