Sweet Stocking stuffer, Christmas gift Great chemistry gift Amazing science gift The Facts of Boron Boron element 5 is a chemical element. Boron is a silvery-black metalloid. Boron Nitride’s hardness is second only to diamond, but it has better thermal (melting point of 3,767F) of and chemical stability, hence boron nitride ceramics are used in high-temperature equipment. Boron is an essential nutrient for all green plants. Boron in its crystalline form is very unreactive. Amorphous boron is reactive. Boron is used to dope silicon and germanium semiconductors, modifying their electrical properties. Boron oxide (B2O3) is used in glassmaking and ceramics. Borax (Na2B4O7.10H2O) is used in making fiberglass, as a cleansing fluid, a water softener, insecticide, herbicide and disinfectant. Boron compounds such as borax (sodium tetraborate, Na2B4O7·10H2O) have been known and used by ancient cultures for thousands of years. Boron does not generally make ionic bonds, it forms stable covalent bonds. Boron can transmit portions of infrared light. Boron's conductivity improves markedly at higher temperatures. Boron carbide (B4C) is used in tank armor and bullet proof vests. Boron nitride nanotubes can have a similar structure to carbon nanotubes. BN nanotubes are more thermally and chemically stable than carbon nanotubes and, unlike carbon nanotubes, boron nitride nanotubes are electrical insulators. Best offer is only for ordering multiples. Safety / Caution Do not attempt to brake open to retrieve metal. I sell the same sample in vials for cheaper.
