High Purity Hydrogen Gas

Hydrogen is a colorless, tasteless, odorless, non-toxic, flammable gas. Melting point -259.2°C, boiling point -252 77°C, relative density (O°C, air = 1) 0 06960. Our high-purity hydrogen stands out for its excellent purity. After strict production process and sophisticated purification technology, its purity can be as high as 99.999% or more, ensuring reliability and stability in various critical applications.
High-purity hydrogen is mainly used in the manufacture of large-scale integrated circuits, and provides a reducing atmosphere as a base gas for the preparation of mixed gases such as SiH4/H2, PH3/H2, B2 H6/H2, etc.

Advantages

Ultra-high purity:
The high-purity hydrogen we provide can reach a purity of more than 99.999%. This means that the impurity content is extremely low, which can ensure stable and reliable performance in various applications. For example, in the electronics industry, high-purity hydrogen can avoid contamination of precision electronic components such as semiconductor chips and ensure product quality.

Safe and reliable:
High-purity hydrogen undergoes strict quality testing and safe handling, reducing potential safety risks. The explosion limit range of hydrogen is 4.0% - 75.6% (volume concentration). Our high-purity hydrogen takes a series of safety measures during storage and transportation to ensure that it does not enter the explosion limit range.

Efficient energy:
Hydrogen has a high energy density and a combustion calorific value of about 142 MJ/kg. It is an efficient energy carrier. In some energy application fields, such as fuel cell vehicles, high-purity hydrogen can provide strong power output while reducing energy consumption costs.

Clean and environmentally friendly:
The only product of hydrogen combustion is water, without any pollutant emissions, which is a very clean energy source. As the world's environmental protection requirements become increasingly stringent, the advantages of high-purity hydrogen as a clean energy source are becoming more prominent. It can help reduce greenhouse gas emissions and alleviate climate change issues.

Applications

Semiconductor manufacturing: In the process of large-scale and ultra-large-scale integrated circuit production, a large amount of high-purity hydrogen or even ultra-high-purity hydrogen is needed as the base gas for configuring mixed gases such as silane and hydrogen. For example, in the process of epitaxial growth and chemical vapor deposition in chip manufacturing, high-purity hydrogen can provide a stable reducing atmosphere to prevent the formation of an oxide layer on the surface of the wafer, ensuring the performance and quality of semiconductor devices.

Protective gas: In the high-temperature processing of certain metals, hydrogen is used as a protective gas to prevent the metal from being oxidized. For example, in the production of cold-rolled silicon steel sheets and the annealing of copper products, high-purity hydrogen can create an oxygen-free environment to prevent the metal from reacting with oxygen at high temperatures and ensure the performance and quality of the metal.

Beverage processing: In some beverage production processes, high-purity hydrogen can be used to remove oxygen from beverages, prevent the ingredients in the beverages from being oxidized, and extend the shelf life of the beverages.

Rocket fuel: High-purity hydrogen can be used as rocket fuel. Hydrogen in liquid form is combined with liquid oxygen to form a liquid hydrogen-liquid oxygen fuel combination, which has a high specific thrust and can provide powerful power for rocket launches and spacecraft. For example, in space launches, liquid hydrogen is often used as one of the main fuels.

Fuel cells: Hydrogen is an important energy source for fuel cells. When combined with oxygen, it produces electricity and water, has no carbon emissions, and is suitable for electric vehicles and fixed power stations. High-purity hydrogen can improve the efficiency and performance of fuel cells and reduce the damage of impurities to fuel cell electrodes.

Glass industry: In float glass production, the strong reducing property of high-purity hydrogen can remove residual oxygen in the high-temperature processing of glass, prevent glass from oxidizing during melting and cooling, and improve the quality and transparency of glass.
