Zinc bromide (ZnBr₂) is an inorganic chemical compound widely used in industrial applications due to its high solubility, density, and chemical stability. It appears as a white crystalline solid under standard conditions and is commonly utilized in oil and gas drilling fluids, batteries, chemical synthesis, and pharmaceutical processes. Because of its unique thermal and physical characteristics, zinc bromide has gained importance in various industrial sectors.
As a trusted manufacturer, supplier, and exporter, SNDB focuses on delivering high-quality zinc bromide products that meet industrial standards and application requirements.
What is Zinc Bromide?
Zinc bromide is formed through the reaction of zinc metal or zinc oxide with hydrobromic acid. Its chemical formula is ZnBr₂, and it belongs to the family of zinc halides. The compound is highly hygroscopic, meaning it readily absorbs moisture from the environment.
The material dissolves easily in water, producing concentrated solutions often used in dense brines and energy storage systems.
Thermal Properties of Zinc Bromide
1. Melting Point
Zinc bromide has a relatively high melting point of approximately 394°C, indicating good thermal stability for industrial processing applications.
2. Boiling Point
The compound exhibits a boiling point around 697°C, making it suitable for operations involving elevated temperatures.
3. Heat Stability
Zinc bromide remains chemically stable under controlled thermal conditions. Excessive heating may lead to decomposition or release of bromine-containing vapors, requiring proper handling and ventilation.
4. Thermal Conductivity
The thermal conductivity of zinc bromide is moderate, allowing effective use in chemical systems where controlled heat transfer is required.
5. Hygroscopic Behavior Under Heat
Because zinc bromide strongly absorbs moisture, temperature changes can influence its water content and concentration in solutions. This property is especially important in industrial storage and transportation.
