In electronic semiconductor manufacturing, nitrogen serves as a fundamental and essential auxiliary material. Its primary functions are to provide a high-purity inert environment, control process parameters, and ensure yield and reliability; these roles span the entire workflow, from wafer fabrication through packaging and testing.

Nitrogen blanketing for storage tanks, pipeline purging, and inert protection for reactors—a purity level of 95% to 99.9% is sufficient to meet safety and anti-corrosion requirements. As nitrogen is inert, non-flammable, dry, and stable, it serves as an essential utility throughout the entire refining and chemical plant.

Bright annealing, powder metallurgy sintering, and carburizing—processes aimed at preventing oxidation and enhancing surface quality—commonly utilize nitrogen with a purity of 99.9% or higher. As an inert, non-oxidizing, non-decarburizing, colorless, and odorless gas, nitrogen serves as the most versatile protective atmosphere in heat treatment applications. Its core functions revolve around preve...

Modified Atmosphere Packaging (MAP) for fruits, vegetables, and meats; nitrogen-flushed packaging for potato chips and coffee; and oxygen displacement for beer and beverages—all designed to extend shelf life, typically utilizing nitrogen with a purity of 95% to 99%.

The pharmaceutical industry demands extremely high purity levels: 99.9% to 99.999% medical-grade high-purity nitrogen—sterile, oxygen-free, inert, and effective in preventing oxidation and spoilage.

Applications such as underground coal mine fire inerting, oilfield nitrogen injection for enhanced oil recovery, and shipboard/firefighting nitrogen generation systems typically utilize nitrogen concentrations ranging from 95% to 99.5%. Nitrogen is inert and non-flammable; it extinguishes fires through asphyxiation, isolates oxygen, and provides protection against static electricity and explosions...
