Boron is an enigmatic metal that can exist as a number of different forms (allotropes) each with different physical and chemical properties. Amorphous boron is a lightweight, but hard brown powder that is generally produced via a reduction of boron oxide with magnesium.
SMI Ltd. stocks and supplies both 95% and 99% min. amorphous boron powder. Our higher purity (99% min.) boron powder contains less than 1.5% magnesium and has an average particle size of between 1-5 microns.
