Key Product Specifications

Purity Grades & Impurity Control

We provide a comprehensive range of HBr gas purities tailored for various industrial and high-end manufacturing applications, ensuring stringent impurity control across all grades:

l Industrial Grade (≥99.0%)

Suitable for basic chemical synthesis and the production of inorganic bromide raw materials, providing stable impurity indicators and cost-effective performance for large-scale industrial manufacturing.

l CP Grade (99.8% to 99.99%)

A high-performance, cost-effective grade designed for fine chemicals and pharmaceutical intermediate production.Strictly controlled impurities: H₂O ＜ 1 ppm, HCl ＜ 0.5 ppm, metal ions ＜ 10 ppb, meeting the precise requirements of delicate chemical reactions.

l Electronic Grade (99.999% - 99.9999%, 5N/6N)

Designed for high-precision semiconductor etching processes. Using advanced rectification and adsorption purification, impurities are tightly limited to CO & CO₂ ≤ 0.3 ppm, metal ions ≤ 1 ppb, with ultra-low moisture and residual gas content. This grade provides an eco-friendly alternative to traditional fluorocarbon etching gases, essential for chip manufacturing and precision electronic processing.

1. Physical & Chemical Properties

Properties of Anhydrous Hydrogen Bromide

Anhydrous Hydrogen Bromide (HBr) is a highly corrosive, acidic gas that exhibits excellent stability when stored under sealed, light-protected conditions. At room temperature and pressure, it appears as a colorless, transparent gas with a sharp, pungent odor. It is highly soluble in water (193g/100mL at 20℃) and is miscible in all proportions with water, ethanol, and various organic solvents. Its aqueous solution, hydrobromic acid, is a strong acid—significantly more potent than hydrochloric acid.

Operational Precautions:

l Stability: HBr gas may decompose under high temperatures or intense light, releasing toxic bromine vapor.

l Storage: Aqueous solutions may discolor (turning yellow to brown) over time due to oxidation and bromine precipitation.

l Safety: Industrial handling requires precise gradient dilution to prevent violent exothermic reactions and ensure operational safety.
