What is Hydrogen bromide gas?

Hydrogen bromide (HBr) is a colorless, corrosive gas with a sharp, irritating odor. It is one of the most important specialty gases used in modern industrial processes, particularly in semiconductor manufacturing and chemical synthesis.

At standard temperature and pressure, hydrogen bromide is highly soluble in water, forming hydrobromic acid. It is a strong acid that reacts violently with bases and many metals, making proper handling and storage essential. In the semiconductor industry, high-purity hydrogen bromide (99.999% grade) is widely used as an etching gas for silicon wafers, especially in the production of advanced logic chips and memory devices.

Real-World Application Case: Recently, we supplied 5N-grade hydrogen bromide to a leading memory chip manufacturer in South Korea for their 14nm DRAM production line. Our gas consistently delivered uniform etching rates across 300mm wafers, helping the customer improve their production yield by 2.3% compared to their previous supplier.

Other key applications of hydrogen bromide include:

• Production of brominated compounds for pharmaceuticals and agrochemicals

• Catalyst in organic synthesis reactions

• Calibration gas for environmental monitoring systems

• Metal surface treatment and refining

Wenzhou Yingyue New Materials Co., Ltd. supplies high-quality hydrogen bromide gas in 47L, 470L and 926L steel cylinders to meet the diverse needs of customers worldwide. All our products are manufactured in compliance with ISO 9001 and DOT standards and undergo rigorous quality testing before delivery.
