High Purity Superfine Boron Powder Amorphous B Powder CAS 7440-42-8 CAS NO.7440-42-8

High Melting Point: Boron has a melting point of 2,076°C, making it suitable for high-temperature applications.

Low Density: It is lightweight compared to many metals, which makes it advantageous for use in lightweight materials and alloys.

Hardness: Boron is extremely hard and is a key component in creating super-hard materials like boron carbide.

Neutron Absorption: Boron’s ability to absorb neutrons without forming long-lived radioactive isotopes makes it vital for radiation shielding and nuclear control rods.

High Thermal Conductivity: It efficiently conducts heat, which is beneficial for thermal management in electronics and other high-temperature systems.

Boron powder is a fine, gray to black amorphous or crystalline material made from the element boron. It is a metalloid known for its high hardness, low density, and unique chemical and thermal properties. Boron is widely used in various industries, including metallurgy, ceramics, electronics, and energy storage, due to its high melting point, excellent thermal conductivity, and strong neutron absorption capabilities.

Application

1. Metallurgy: Boron is used as an alloying agent in steel and other metals to improve hardness, tensile strength, and resistance to wear. Boron steel is particularly valued in automotive and construction industries for making strong and lightweight components.

2. Ceramics: Boron powder is an essential ingredient in boron carbide (B?C), a material used in abrasive tools, cutting tools, and armor systems due to its extreme hardness (third hardest material after diamond and cubic boron nitride).

3. Electronics: Boron is a dopant in semiconductors to alter electrical properties, particularly in silicon wafers. It enhances the performance of p-type semiconductors used in transistors, diodes, and integrated circuits.

4. Energy Storage: Boron is used in advanced energy storage materials like lithium boron batteries, where it improves the battery’s energy density and longevity.

5. Nuclear Industry: Due to its high neutron absorption cross-section, boron is used in nuclear reactors as a control material. Boron compounds (like boron carbide) are used in neutron shields and radiation protection gear.

6. Chemical Reactions: Boron powder is utilized as a catalyst in organic chemistry for specific reactions and is also used in pyrotechnics for producing bright green flames in fireworks and flares.
