Product Name:Boron
English Name:Boron
CAS No.:7440-42-8
Aliases:Boron powder, Amorphous boron, Crystalline boron, High-purity boron powder
Molecular Formula:B
Physical Properties:Amorphous boron is a brownish-black powder; crystalline boron is a silver-gray solid with metallic luster. Crystalline density: 2.34–2.46 g/cm³; melting point: approximately 2076°C; boiling point: approximately 3927°C. It is extremely hard and has semiconductor characteristics. Insoluble in water; soluble in hot concentrated nitric acid, concentrated sulfuric acid and other strong oxidizing acids; reacts with molten alkali to form borates. Chemically stable at room temperature; reacts with oxygen, nitrogen, carbon and halogens at high temperatures.
Uses:Boron is widely used in metallurgy as a deoxidizer and alloy additive for producing high-strength materials such as boron steel and boron fiber. It serves as a semiconductor dopant in the electronics industry. High-purity boron is used to manufacture boron-based compounds, ceramics and refractory materials, and acts as a neutron absorbent in the nuclear industry.
