beryllium oxide

chemical compound
Also known as: beryllia

Quick Summary

Beryllium oxide (BeO) is a white, amorphous compound with high thermal conductivity and electrical resistance. It is derived from beryl ore and primarily used as a high-temperature refractory material, such as in crucibles, and in phosphors for various equipment. Beryllium itself is the lightest alkaline-earth metal, known for its use in metallurgy as a hardening agent and in specialized applications like outer space and nuclear technology. Beryllium oxide, also known as beryllia, has a high melting point and is valued for its unique combination of electrical resistance, dielectric strength, and thermal conductivity, making it useful in ceramic ware for rocket engines and high-temperature nuclear devices.12
