High-purity Metallic Boron

Generic names Metallic boron, boron
Chemical formula B
Packing / shipping method 50-gram polyethylene bottles

Product overview

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.

General applications

Additive for single-crystalline silicon (acceptors and dopants for p-type semiconductors)

Special characteristics

・High-purity metallic boron is used to manufacture p-type single-crystalline silicon

・Tokuyama is one of the limited companies that manufacture metallic boron for use in semiconductor-grade silicon

・Non-toxic, odorless, grayish-black colored crystals

・The melting point of metallic boron is 2,300°C, and is higher than that of polycrystalline silicon
