Boron granules are black or dark gray in color and exhibit high chemical stability. They have a hardness of approximately 9.3 on the Mohs scale, and a relatively low density (about 2.34 g/cm³). At room temperature, boron granules maintain strong chemical stability but show good chemical reactivity at elevated temperatures, reacting with oxygen and nitrogen.

Key Features

• High Hardness: With a Mohs hardness of 9.3, suitable for applications requiring high hardness.
• Excellent Chemical Stability: Remains stable under normal temperature conditions.
• Reactivity: Shows higher chemical reactivity at elevated temperatures, especially with oxygen and nitrogen.
• Versatile Applications: Widely used across aerospace, metallurgy, and chemical industries.

Applications

Boron granules are utilized in various industries, including:

• Aerospace: Used in solid rocket propellants to enhance engine specific impulse.
• Metallurgy: Employed as a reducing agent for metal refining.
• Chemical Industry: Used in the production of borax, boric acid, and other chemical products.
• Nuclear Industry: Acts as a control rod material in nuclear reactors, benefiting from its excellent neutron absorption capabilities.
