High Purity Boron powder | B

 

Introduce:
High Purity Boron powder is a kind of dark brown powder or grey lustrous crystal. Relative density: 2.35g/cm3, Melting point: 2300℃, Boiling point: 2550℃. Oxidation reacted when heated to 300℃, Ignition point: 700℃. High Purity Boron powder is insoluble in water, hydrochloric acid, alcohol and ether. It can be soluble in cold strong alkali but with hydrogen gas decomposed out. Boracic acid formed when oxidized by strong sulfuric acid or strong nitric acid. Reacted with oxygen, nitrogen, sulfur and halogen when heated to high temperature. High Purity Boron powder can be directly reacted with some metals to form Boride.
Boron is the only p-dopant for silicon and additionally 11B is one of the best neutron reflectors available, being utilized when neutron absorption is not desired.
