Amorphous boron is used as a raw material for numerous chemical products. It is processed for solid fuels and igniters and added to welding and soldering pastes. It is also used in the automotive industry as a pyrotechnical component in the igniters and gas generators of airbags. Boron is also used as an alloy component. It is also contained in neodymium-iron-boron magnets (NdFeB magnets), which are characterized by the highest adhesive forces with the smallest volume. They are used in motors, loudspeakers, wind turbines and cars.
Due to its high hardness, boron is also used in high-performance ceramics. In nano form, it is a component in the production of superconductors for the high-temperature range. Boron carbide is considered one of the hardest materials in the world after diamonds and is very wear-resistant. This makes it an ideal material in the fields of mechanical engineering, metallurgy, the automotive industry, aviation technology and ballistics, where it is used in the form of boron carbide plates. The industry also uses boron carbide as an abrasive and lapping agent for processing extremely hard materials. Boron nitride is used as an abrasive because of its hardness.
