DescriptionBoron is a trivalent, nonmetallic element that occurs abundantly in the evaporite ores, borax and ulexite. Boron is never found as a free element on Earth. Boron as a crystalline is a very hard, black material with a high melting point, and exists in many polymorphs. Boron has several forms, the most common form being amorphous boron, a dark powder, non-reactive to oxygen, water, acids, and alkalis. It reacts with metals to form borides. Boron is an essential plant micronutrient. Sodium borateCertificatesBasic Info

Storage Conditions:Store in a cool, dry place. Keep container closed when not in use.
Vapor Pressure:1.56X10-5 atm (0.0119 mm Hg) at 2140 deg C
Experimental Properties:Atomic number 5; naturally-occurring isotopes: 10,11; three short-lived artificial isotopes: 8,12, 13|Alpha-rhombohedral form, 12 atoms/unit cell; beta-rhombohedral form, 105 atoms/unit cell; alpha-tetragonal form, 50 atoms/unit cell|The alpha-rhombohedral form of boron is the simplest crystal structure with slightly deformed cubic close packing, which degrades at 1200 °C and at 1500 it converts to beta-rhombohedral boron, which is the most thermodynamically stable form.|Crystalline boron is very inert. Low purity, higher temperature, and changes in or lack of crystallinity all increase the chemical reactivity.|For more Other Experimental Properties (Complete) data for BORON, ELEMENTAL (9 total), please visit the HSDB record page.
