Nano Boron Powder/Crystal Boron Powder

Boron is a metalloid element, having two allotropes, amorphous boron and crystalline boron. Amorphous boron is a brown powder while crystalline boron is silvery to black. Crystalline boron granules and boron pieces are high purity boron, extremely hard, and are poor conductor at room temperature.

Crystalline Boron

The crystal form of crystalline boron is mainly β-form, which is synthesized from β-form and γ-form into a cube to form a fixed crystal structure. As a naturally occurring crystalline boron, its abundance is over 80%.The color is generally gray-brown powder or brown irregular shaped particles. The conventional particle size of the crystalline boron powder developed and customized by our company is 15-60μm; the conventional particle size of crystalline boron particles is 1-10mm (special particle size can be customized according to customer needs). Generally, it is divided into five specifications according to purity: 2N, 3N, 4N, 5N, and 6N.

 Package:It is usually packed in polytetrafluoroethylene bottles and sealed with inert gas, with specifications of 50g/100g/bottle;

Amorphous Boron

Amorphous boron is also called non-crystalline boron. Its crystal form is α-shaped, belonging to the tetragonal crystal structure, and its color is black brown or slightly yellow. The amorphous boron powder developed and customized by our company is a high-end product. After deep processing, the boron content can reach 99%, 99.9%; the conventional particle size is D50≤2μm; according to the special particle size requirements of customers, sub-nanometer powder (≤500nm) can be processed and customized.

What are Amorphous boron, Boron powder and Natural boron used for?

There are wide applications for Amorphous boron, Boron powder and Natural boron. They are used in metallurgy, electronics, medicine, ceramics, nuclear industry, chemical industry and other fields.

1. Amorphous boron is used in the automotive industry as an igniter in airbags and belt tighteners. Amorphous boron is used in pyrotechnics and rockets as an additive in flares, igniters and delay compositions, solid propellant fuels, and explosives. It gives the flares a distinctive green color.        

2. Natural boron is composed of two stable isotopes, one of which (boron-10) has a number of uses as a neutron-capturing agent. It is used as a neutron absorber in nuclear reactor controls, and radiation hardening.

3. Elemental boron is used as a dopant in the semiconductor industry, while boron compounds play important roles as light structural materials, insecticides and preservatives, and reagents for chemical synthesis.

4. Boron powder is a kind of metal fuel with high gravimetric and volumetric calorific values, which has been widely used in military fields such as solid propellants, high-energy explosives, and pyrotechnics. And the ignition temperature of boron powder is greatly reduced due to its irregular shape and large specific surface area;

5. Boron powder is used as an alloy component in special metal products to form alloys and improve the mechanical properties of metals. It can also be used to coat tungsten wires or as fillaments in composites with metals or ceramics. Boron is frequently used in spcial purpose alloys to harden other metals, specifically high-temperature brazing alloys. 

6. Boron powder is used as a deoxidizer in oxygen-free copper smelting. A small amount of boron powder is added during the metal smelting process. On the one hand, it is used as a deoxidizer to prevent the metal from being oxidized at high temperature. Boron powder is used as an additive for magnesia-carbon bricks used in high temperature furnaces for steelmaking;

7. Boron Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas.

8. Boron powder is also an important raw material for the manufacture of high-purity boron halide, and other boron compound raw materials; Boron powder can also be used as welding aid; Boron powder is used as an initiator for automobile airbags;
