The boron content inside the earth’s crust is 0.001%. Boron is a black or silver-grey strong. The crystalline boron is black, its hardness is only decreased than diamond, and its texture is brittle. Boron is called after Arabic, meaning “flux.” It says that the historical Arabs already knew that borax could melt metal oxides and used it as a flux in welding.
Boron is a black or darkish brown powder, which prevents the inner boron from persevering with to oxidize because of the formation of a boron trioxide movie during oxidation inside the air. Boron powder can react with fluorine at normal temperature without being corroded by hydrochloric acid and hydrofluoric acid aqueous solution. Boron isn’t soluble in water, and powdered boron is soluble in boiling nitric acid and sulfuric acid.
Characteristics of amorphous boron powder:
The chemical characteristics of amorphous boron powder are more energetic than those of crystalline elemental boron. Due to the fact crystalline boron may be very hard, it’s far frequently used in place of a diamond to make reducing gear or drill bits. At some point in the metal smelting procedure, a small quantity of boron is brought as a deoxidizer, on the one hand, to save you oxidation of the metallic at high temperatures; alternatively, it forms an alloy to improve the mechanical houses of the metallic. For example, boron copper is used to making manipulate rods for atomic reactors.
Amorphous boron powder becomes a vital strength material, and its utility in reliable composite fuels has already been valued. As a strong fuel, the calorific fee of boron is a whole lot greater than double that of carbon, about two times that of aluminum, and more than twice that of magnesium. The volumetric calorific value is sort of three instances that of hydrocarbon fuels, and its density is best barely lower than aluminum.
Amorphous boron powder has the very best calorific cost. As a long way as its strength is worried, boron must be the first-rate non-steel fuel. And due to its irregular shape and big precise floor place, the ignition temperature of amorphous boron is significantly decreased.
Application of amorphous boron powder:
1. For pyrotechnic components, boron needs to be the excellent non-metal gas in terms of its electricity. And due to its irregular shape and massive specific floor area, the ignition temperature of boron powder is substantially reduced;
2. Boron powder is likewise a crucial uncooked fabric for the manufacturing of high-purity boron halide, and different boride raw materials are prepared;
3. Oxygen-free copper smelting deoxidizer, adding a small amount of boron powder at some point of metal smelting, on the only hand, it acts as a deoxidizer to prevent the metal from oxidizing at excessive temperatures;
4. As an alloy issue in unique metallic products, shape alloys to enhance the mechanical residences of metals.
5. Boron powder also can be used as welding useful resource;
6. solid rocket fuel;
7. vehicle airbag initiator;
8. Magnesium-carbon brick additive for steelmaking high-temperature furnace;
