| Beryllium oxide | Beryllium oxide (BeO) is a white crystalline oxide. It is obtained from beryllium or beryllium compounds by ignition in the air. The sintered beryllium oxide (beryllia), which is very stable, has ceramic characteristics. It is similar to aluminium oxide (Al2O3), is highly fire resistant (melting point: 2570°C), and has polymorphism. (references) | ||

| Beryllium oxide | Mining | A white powder; hexagonal; BeO. Used in the preparation of beryllium compounds and in ceramics and refractories. Melting point, 2,570 degrees C; and sp gr, 3.02. Bodies high in BeO have extremely high thermal conductivity (in the range of metals) and also possess high mechanical strength. Used in nuclear reactors because of its refractoriness, high thermal conductivity, and ability to act as a moderator for fast neutrons, reducing them to thermal speeds. Beryllia ceramics are used for electronic components and for crucibles for melting uranium and thorium. Syn: bromellite. (references) | |
