Are you familiar with Boron? Boronhas the largest volumetric heat, and its gravimetric heat is second only to beryllium. Slightly soluble in nitric acid, insoluble in water.Amorphous boron is chemically active. Powder and air can form explosive mixtures. Preparation of amorphous boron by reducing boron anhydride with magnesium.For solid ramjets and smokeless clean propellants. Elemental boron is black or dark brown powder. When oxidized in air, the formation of boron trioxide film hinders the internal boron from continuing to oxidize. It can react with fluorine at room temperature and is not corroded by aqueous hydrochloric acid and hydrofluoric acid. Boron is insoluble in water, powdered boron is soluble in boiling nitric acid and sulfuric acid, and most molten metals such as copper, iron, manganese, aluminum and calcium.
The Physical and chemical properties of Boron Gray-black shiny crystals. The relationship between temperature and crystal form is: >1300°C is high-temperature rhombohedral (β-type); 1000-1300°C is tetragonal crystal; 800-1000°C is low-temperature rhombohedral (α-type). The relative density is 2.34~2.37. The melting point is 2300°C, and the sublimation temperature is 2550°C. Insoluble in water, hydrochloric acid, ethanol, and ether. Soluble in cold concentrated alkali solution and decomposed hydrogen. It can be oxidized into boric acid by concentrated nitric acid, concentrated sulfuric acid, and aqua regia. The chemical properties are relatively lively. It is stable in the air, and at room temperature, it will be oxidized when heated to 300°C, and it will catch fire at 700°C. When burning, the flame is red, and the flame of trace gasified boron is green. It can interact with oxygen, nitrogen, sulfur, halogen and carbon at high temperature. It can be directly combined with many metals to form metal borides. Reaction with organic compounds can generate -B-C- or -B-O-C- compounds.
The natureof Boron brown powder. The relative density is 1.73, the melting point is 2190°C, and the boiling point is 3660°C. Unaffected by water, bromine and chlorine at certain temperatures. Unburned boron can be absorbed in hot nitric acid, sulfuric acid and molten metals, such as iron, magnesium and aluminum, etc., and is insoluble in water. The electrical conductivity is low at room temperature, and the electrical conductivity is high at high temperature, and the electrical conductivity can be increased after doping with trace carbon. Contact with hydrogen iodide can explode. Powder and air can form an explosive mixture, and when it reaches a certain concentration, it will explode when it encounters Mars.
Applications of Boron Boron powder can be used in superconducting materials, amorphous alloy materials, aerospace alloy materials, electronic materials, chemical anti-corrosion materials, ceramics, enamel glazes, and nuclear leakage prevention materials. It is used as a dopant for semiconductor material silicon, a high temperature and high power semiconductor device material, and an infrared device material. Adding boron powder to the metal can produce aircraft brake pads, welding materials, boride alloys, and amorphous materials. The special steel made of metal added with boron powder can effectively improve the wear resistance of the mechanical industry transmission grinding system. Adding a certain amount of boron powder in glass industry processing can increase the strength of glass by more than ten times. High-purity boron powder can also be used to process and manufacture drilling tools, replacing various industrial carbide drilling tools. Boron powder is widely used in military, machinery, aerospace, chemical, pharmaceutical and other industries.
