Product Description

Product Description
High-purity Oxygen is commercially produced by air compression, liquefaction and fractional distillation. Ultra-high purity oxygen requires secondary deep purification and fine distillation.
It can also be obtained by water electrolysis, and membrane separation is used for low and medium purity products. Widely applied in semiconductors, medical care, welding, chemicals, metallurgy, environmental protection, scientific research and new energy, oxygen acts as a key material for combustion, oxidation, electronic processing and laboratory testing. High-purity grades serve optoelectronics, semiconductor and pharmaceutical industries, and industrial oxygen is commonly used in steelmaking, machinery and petrochemicals.
