Boron pieces, <20 mm, 99.5%

Boron is a metalloid chemical element with symbol B and atomic number 5.

B 1967 (OTTO) Boron pieces <20 mm, 99.5% Cas 7440-42-8 - used as a dopant for such semiconductors as silicon, germanium, and silicon carbide. Having one fewer valence electron than the host atom, it donates a hole resulting in p-type conductivity.
