boron powder amorphous
Boron exists as two main allotrope forms Amorphous boron brown powder, similar in aspect with cocoa powder. This one in turn consists of two forms powder (brown-black) and glassy (opaque black). Crystalline boron black, extremely hard (about 9.5 on the Mohs scale). It is a poor electrical conductor at room temperature.

In fact, the reduction of excess of either boron sesqui-oxide or borax with a suitable metallic reducing agent always leads to the production of an amorphous, brown powder containing oxygen. Weintraub refers to such a product as boron suboxide; it is most probably a solid solution of an oxide of boron, possibly B 4 O 3, in boron.
