What is Amorphous Boron Powder?
Boron Powder, amorphous element boron, CAS No. is 7440-42-8, appearance is light brown to gray-black invisible powder, melting point is 2300℃± 2℃, atomic weight 10.81, L Hua temperature 2550℃, specific gravity 2.34-2.37, insoluble in water, hydrochloric acid, ethanol and ether, soluble in cold concentrated alkali solution to decompose hydrogen, and oxidized by concentrated sulfuric acid and concentrated nitric acid Into boric acid.

Properties of Amorphous Boron Powder
In the periodic table, boron is in a special position between metals and non-metals. It has strong negative charge, small atomic radius, concentrated nuclear charge, and more active chemical properties. It is very stable at room temperature. It will be oxidized when heated to 300℃, and will smell at 700℃. In addition, at high temperature, it can interact with oxygen, nitrogen, sulfur, halogen and carbon, and can also interact with Many metals combine directly to form borides.
Applications of Amorphous Boron Powder
Amorphous boron powder is often used in metal smelting, electronic product manufacturing, ceramic manufacturing, chemical industry and nuclear industry, etc. The specific uses of Amorphous Boron Powder are as follows:
1. Additives for pyrotechnics, in terms of energy, Amorphous Boron Powder should be the best non-metallic fuel. The ignition temperature of Amorphous Boron Powder is greatly reduced due to its irregular shape and large specific surface area;
2. Amorphous Boron Powder is also an important raw material for the production of high-purity boron halide and other boride raw materials;
3. Oxygen-free copper smelting deoxidizer, a small amount of Amorphous Boron Powder is added in the metal smelting process, on the one hand, it is used as a deoxidizer to prevent the metal from oxidizing at high temperatures;
4. Amorphous Boron Powder can be used as an alloy component in special metal products to form alloys and improve the mechanical properties of metals.
5. The chemical properties of Amorphous Boron Powder are more active than crystalline elemental boron. Crystalline boron is very hard, and it is often used instead of diamond to make cutting tools or drill bits.
6. Amorphous Boron Powder can also be used as a welding aid;
7. Amorphous Boron Powder is an important energy material. It is used as a solid fuel in composite solid propellants. The calorific value of boron is more than twice that of carbon, about twice that of aluminum and more than twice that of magnesium. The calorific value is almost three times that of hydrocarbon fuel, the density is only slightly lower than that of aluminum, and it has the highest volumetric calorific value. In terms of its energy, boron should be the best non-metallic fuel. In addition, the ignition temperature of amorphous boron is greatly reduced due to its irregular shape and large specific surface area.
8.Amorphous boron powder can be used as an additive for magnesia carbon bricks for steelmaking high-temperature furnaces.
