Boron - Infogalactic: the planetary knowledge core

2018-8-20 · Boron is a metalloid chemical element with syol B and atomic nuer 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in both the Solar system and the Earth''s crust. Boron is concentrated on Earth by the water-solubility of its more common naturally occurring compounds, the borate minerals.

Boron : Wikis (The Full Wiki)

Boron is similar to carbon in its capability to form stable covalently bonded molecular networks. Even nominally disordered boron contains regular boron icosahedra which are, however, bonded randomly to each other without long-range order.[7] [8] Crystalline boron is a very hard, black material with a high melting point of above 2000 °C.It exists in four major polymorphs: α, β, γ and T.
