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.
Crystalline boron is used in nuclear technology as a neutron absorber in control rods and for neutron shields in nuclear reactors. In addition, high-purity boron is used both to manufacture high-purity metal borides in the semiconductor industry and for thermistor filaments. Synthetic materials and light metals (composite materials) strengthened with boron fibers are also used in the aerospace industry.
H.C. Starck offers crystalline boron in three different qualities with a boron content from 98.0 percent to at least 99.4 percent.
