Properties, occurrence, and uses. Pure crystalline boron is a black, lustrous semiconductor; i.e., it conducts electricity like a metal at high temperatures and is almost an insulator at low temperatures. It is hard enough (9.3 on Mohs scale) to scratch some abrasives, such as carborundum, but too brittle for use in tools.

This was made possible through the use of extreme laser pulses for boron fusion. Laser-driven ignition of HB11 using thermal compression by standard nanosecond laser pulses requires compression of the HB11 fuel to 100,000 times its solid density. Therefore, until now, HB11 fusion has appeared unfeasible.

Boron - Compounds, Uses, Properties: In its compounds boron shows an oxidation state of +3. The first three ionization energies of boron, however, are much too high to allow formation of compounds containing the B3+ ion; thus, in all its compounds boron is covalently bonded. That is, one of boron's 2s electrons is promoted to a 2p orbital, giving …
