- Boron carbide (B4C): A hard and very wear-resistant material that is used for abrasive applications and as a component in some heat-resistant materials.
- Boron nitride (BN): A white solid that is a good electrical insulator and thermal conductor, and is used in applications such as high-temperature insulators, solid lubricants and semiconductors.
- Boric acid (H3BO3): A weak acid that is used in a variety of applications, including as a fire retardant, an antiseptic and a flux in soldering and brazing.
- Borax (Na2B4O7.10H2O): A white salt that is used in the manufacture of glass, ceramics and detergents, and as a flux in soldering and brazing.
- Boron hydrides: A group of compounds that contain hydrogen and boron, and are used as fuels, rocket propellants and sources of hydrogen.
Boron can also form alloys with other metals, such as aluminium, magnesium and titanium, to improve their properties such as strength, hardness and wear resistance.
