1, application demand: argon and helium have a wide range of applications in many fields, such as scientific research, industrial production, medical equipment and so on. Due to their unique physical and chemical properties, argon and helium are difficult to replace in some specific applications, so the demand is higher, which pushes up their prices.
2, production costs: argon and helium production process is relatively complex, requiring fine separation and purification. These processes require large investments in energy and equipment, thus increasing the production costs of argon and helium.
