BORON - Hardness and purity in one element

Boron has the highest tensile strength and the second highest hardness – only diamond carbon is harder. Under increasing temperatures boron exhibits an above-average increase in its electrical conductivity. The various boron modifications have physical and chemical similarities with carbides, such as silicon carbide or tungsten carbide.

Boron Amorphous
Natural boron can occur as a brown or gray product (amorphous boron) or as crystalline boron in the form of red-brown α-rhombohedral boron or black β-rhombohedral boron. Our product portfolio includes both amorphous and crystalline boron.

Amorphous boron

Due to its special combination of properties as well as the ability to absorb neutrons, large quantities of amorphous boron are used in pyrotechnics. For example, it is to be used as an additive in solid-fuel rocket propellant and explosives, in initiators for airbags and belt pre-tensioners, and as an additive in pyrotechnical mixtures. In addition, as a powerful reducing agent it can also be added to certain soldering agents as a flux or additive. Other application areas include the manufacture of high-purity metal borides and use as a sintering additive for silicon carbide high-performance ceramics.

H.C. Starck offers amorphous boron in three different qualities with a boron content from 86 percent to at least 95 percent.
