monomer boron/ amorphous boron powder CAS 7440-42-8
Boron has several allotropes. Amorphous boron is also called elemental boron and monomer boron.
It is brown powder or gray shiny crystals, and its chemical properties are relatively lively. It is stable
under air and normal temperature. It is oxidized when heated to 300℃ and burns at 700℃, The flame
is red when burning, and the boron flame with trace vaporization is green. Insoluble in water, hydrochloric
acid, ethanol, and ether. It is soluble in cold concentrated alkali solution and decomposes hydrogen,
which is oxidized to boric acid by concentrated nitric acid and concentrated sulfuric acid. At high
temperatures, Boron can interact with oxygen, nitrogen, sulfur, halogens and carbon, Boron can also
directly combine with many metals to form borides. The reaction of boron with organic compounds in
which oxygen exists between boron and carbon.
Single boron is located at a special position on the dividing line between metals and non-metals in the
periodic table. It is a non-metallic element with a strong negative charge, small atomic radius, concentrated
nuclear charge, and non-metallic properties similar to sillicon. Its density is 2.35g/cm3. Hardness is 9.3,
Specific gravity is 2.33 - 2.45, melting point 2300℃, bolling point 2550℃.
