Specification AgeRangeDescription : adult Brand : LIFEYYZG BulletPoint1 : 4N high-purity boron small block is irregular block, purity B ≥ 99.99%, self-sealing bag packing. BulletPoint2 : Boron is a non-metallic element, the periodic table, cycle 2, group ⅢA elements, atomic number 5, relative atomic mass 10.811, melting point of about 2076 ℃, boiling point of 3927 ℃, the density of 2.34g/cm³. BulletPoint3 : Boron has amorphous boron and crystalline boron and other isotopes, amorphous boron is brown, crystalline boron is gray-black, boron in the earth's crust, the content of 0.001%, brittle, with a high hardness of about 9.3. BulletPoint4 : Boron is a weak conductor of electricity at room temperature, and conducts electricity well at high temperatures, so it is also categorized as metalloid, has a high electrical resistance, but its electrical conductivity increases as the temperature rises. BulletPoint5 : Boron and its compounds have a wide range of industrial applications, such as the manufacture of high-temperature-resistant glass, fiber-reinforced composites, semiconductor materials, and neutron absorption in nuclear reactors.
