Formation of Beryllium Oxide

概述

Beryllium reacts with oxygen to form beryllium oxide, an extremely hard and thermally stable ceramic. BeO has the unusual combination of being an excellent electrical insulator while also being a superb thermal conductor, comparable to some metals.

日常示例

Beryllium oxide ceramics are used in high-power electronics as heat sinks, though handling requires safety precautions due to beryllium toxicity.

工业重要性

氧化铍因其极高的导热性（接近某些金属）和优异的电绝缘性，被用于制造半导体器件散热基板、核反应堆中子反射材料和高功率微波电子管。但铍的毒性严重限制了其应用范围，工业处理需严格安全防护。
