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. 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.
