Black amorphous boron powder was isolated from borax by Joseph Louis Gay-Lussac (with Thenard) and independently by Davy in 1808. Hard, red crystals of pure boron were not produced for almost one hundred years. Aluminum borohydride and boron trihydride are used as reducing agents in organic chemistry. Boron is an essential element that is involved in bone formation. It is rapidly absorbed and just as rapidly excreted in the urine. Calcium appears to play a role in influencing Boron absorption.
