Boron Powder Cas 7440 42 8


Boron Nitride is a white powder with high electrical resistance. It is non-combustible and known for excellent heat-shock resistance. It is often used as a high-temperature insulator. Boron Nitride can be used for furnace insulation, crucibles, rectifying tubes, chemical equipment, self-lubricating bushings, molten-metal pump parts, and as a heat shield for plasma. It is also often used for nose cone windows and high-strength fibers. Boron powder, also known as monomeric or elemental Boron, is gray-black or brown amorphous powder. Its chemical properties are lively, tasteless, and odorless. It is stable in the air and at room temperature. It is oxidized when heated to 300°C and burns when it reaches 700°C. The flame is red when burning, and the flame of trace gasified Boron is green. Elemental Boron is insoluble in water, hydrochloric acid, ethanol, ether, sulfuric acid, nitric acid, and molten metal but soluble in cold concentrated alkali solution and decomposes into hydrogen gas, and is oxidized into boric acid by concentrated nitric acid and concentrated sulfuric acid. Boron can interact with oxygen, nitrogen, sulfur, halogen, and carbon at high temperatures. Boron can also be directly combined with many metals to form metal compounds and react with organic compounds to form compounds and substances in which Boron is directly linked to carbon. Or a compound with oxygen between Boron and carbon. Monolithic Boron is in a special position in the periodic table that divides elements into metals and non-metals. It is an element with dominant non-metallicity, strong electronegative properties, small atomic radius, concentrated nuclear charge, and non-metallic properties similar to silicon. Its density is 2.35g/cm3. Hardness 9.3, specific gravity 2.33-2.45, melting point: 2300°C, boiling point: 2550°C.
