Beryllium Oxide - an overview | ScienceDirect Topics

Beryllium oxide (BeO) is a white crystalline oxide. It occurs in nature as the mineral "Bromellite". Historically, beryllium oxide was called glucina or glucinium oxide. It is an electrical insulator and its thermal conductivity is such that it is higher than any other nonmetal except diamond, and actually exceeds that of some metals.
