摘要
采用化学分析、Ｘ射线衍射分析（ＸＲＤ）和差热分析（ＤＴＡ）等方法研究了硼化物化学稳定性及热处理条件对硼提取率的影响。结果表明：硼化物化学稳定性高则硼提取率低，复合氧化物２ＭｇＯ．Ｂ２Ｏ３的化学稳定性最低，因此硼提取率最高；硼渣热处理温度高于１２６０℃或低于１０００℃，硼提取率低，在１１００℃时，硼提取率最高。
The influences of the chemical stability of boride and the heat treatment on the efficiency of extractive boron in the slag were investigated by means of chemical analysis and X-ray diffraction (XRD)as well as differentlal thermal analysis(DTA)。The experimental results indicated that the efficiency of extractive boron decreased as chemical stability of boride increased , al1d the highest of the efficiency of extractive boron belongs to boride 2MgO·B2O3。The efficiency of extractive boron was low while the he...
