What is boron powder? The crystalboron is black, its hardness is second only to diamond, and its texture is brittle. Boron is named Boron, derived from Arabic and originally means "flux". It shows that ancient Arabs knew that borax could melt metal oxides and is used as a flux in welding. Mr10.81 ρ= 2.37g/cm3 (amorphous); 2.34~2.46g/cm3 (crystal), melting point 2177~2301 ℃; The boiling point is 2550~2658 ℃. Boron has the largest heat volume, and the heat weight is only second to beryllium. It is slightly soluble in nitric acid and insoluble in water. Amorphous Boron has active chemical properties. The powder and air can form an explosive mixture. Amorphous Boron is prepared by reducing boron anhydride with magnesium. It is used for solid ramjet engines and smokeless clean propellants. Simple Boron is a black or dark brown powder; during oxidation in air, the formation of boron trioxide film prevents the continuous oxidation of internal Boron. It can react with fluorine at room temperature and is not corrupted by hydrochloric acid and hydrofluoric acid aqueous solutions. Boron is insoluble in water. Powdered Boron can be dissolved in boiling nitric acid and sulfuric acid, as well as most molten metals such as copper, iron, manganese, aluminium and calcium.
Use of boron powder Boron powder is commonly used in metal smelting, electronic product manufacturing, ceramic manufacturing, chemical and nuclear industries, etc. The specific functions and uses of boron nitride are as follows: 1. Boron powder can be used to make various Boron containing compounds, as raw materials for producing boron fibre, and as important raw materials for manufacturing high-purity boron halide; 2. Boron is added in the form of the compound as a gas scavenger for smelting or melting special alloy steel; 3. High energy fuel for spacecraft used in rockets 4. In the electronic industry, it is used as the ignition electrode of the ignition tube 5. Substitute for precious or scarce metals 6. It is a protective material in the atomic energy industry and a control rod in atomic reactors.
Physical Properties of Boron Powder Grey black crystal with lustre. The relationship between temperature and crystal type is as follows: high-temperature diamond when the temperature is higher than 1300 ℃（β- Type); 1000~1300 ℃ is tetragonal crystal; Low-temperature diamond crystal at 800~1000 ℃（α- Type). The relative density is 2.34~2.37. The melting point is 2300 ℃, and the sublimation temperature is 2550 ℃. It is insoluble in water, hydrochloric acid, ethanol and ether. It can dissolve in a cold concentrated alkali solution and decompose hydrogen. It can be oxidized to boric acid by concentrated nitric acid, sulfuric acid and aqua regia. The chemical property is relatively active. It is stable in the air and at room temperature. It is oxidized when heated to 300 ℃ and ignites at 700 ℃. The flame is red when burning, and the slightly gasified boron flame is green. It can react with oxygen, nitrogen, sulfur, and Halogens at high temperatures interacting with carbon. They can directly combine with many metals to form metal borides. They can react with organic compounds to form B-C - or B-O-C – compounds.
