摘　　要：以ＭｇＯ－ＳｉＯ２－Ｂ２Ｏ３三元系代替富硼渣为研究对象，研究了在不同气氛、温度、时间下的挥发．结果表明，该三元系在高温下的挥发与气氛有很大的关系，在还原气氛下，随温度的升高、时间的延长，挥发量明显增加，氧化气氛下挥发量较小．The volatilization of MgO-SiO2-B2O3 ternary system which replaces boron-rich slag was studied in different atmosphere,temperature and time. The result showed that the atmosphere has a great effect on the volatilization of this ternary system,and the volatilization has an obvious increase with raising the temperature and prolonging the time,in a reductive atmosphere.
