Boron is black or dark brown powder with a melting point of 2076℃ and a boiling point of 3927℃. Bron has many allotropes. Amorphous boron is brown powder, while crystalline boron is grayish black. Crystalline boron is inert, while amorphous boron is more active.
High pure halogenated boron, brownish color, 99.9% and 99.99% 3N 4N by bromated synthesizing reduction method can be used for the production of a variety of boron compounds, and as additive in special alloy production. Furthermore, it finds more application in Ultrahigh Speed Integrated Circuit, medicine, ceramics, for high temperature resistant alloy, catalyst, and used as a neutron absorber in nuclear chemical industry.
