High-purity Metallic Boron
High-purity metallic boron is used to manufacture p-type single-crystalline silicon. In order to employ silicon as an electronic component, it is necessary for an electrical current to flow in the proper amount in the silicon. Therefore, additives are used in miniscule amounts when producing single-crystalline silicon from polycrystalline silicon. Metallic boron is used as an additive to make p-type semiconductors, while phosphorous, antimony, and arsenic are used to make n-type semiconductors. These additives as well as the silicon must be of high purity for this process to function.
