The properties, uses and manufacturing processes of beryllium oxide
Properties and uses of beryllium oxide
Beryllium oxide has a melting point of 255 °C and a density of 3.03g/cm3. The stability is excellent when heated, especially the resistance to reduction is strong, of all oxides beryllium oxide is the most resistant to carbon reduction at high temperatures. BeO thermal conductivity is very high, but conductivity is very low. Beryllium oxide at low temperature mechanical strength is relatively small, but at 1600℃, mechanical strength is basically unchanged, is the highest pressure strength of oxides at this temperature.
Based on BeO's good nuclear and high temperature properties, BeO is used in rocket head cone, plasma arc engine frontiers and nozzles, neutron reducers and anti-radiation materials for atomic reactors. BeO porcelain can be used as a leaf for gas permeation. Melt high-purity uranium metal with a BeO crucible. In addition to being used for crucibles, BeO is a refractory material that can be used as a refractory clamping lever for heating elements, protective screen, furnace lining and cathode heating elements. Sheet BeO products with holes and slots, filled with ceramic powder with good thermal stability and used as insulation material. BeO is widely used as a component of coatings or coatings for its high heat resistance and corrosion resistance.
