研究了一种新的X射线衍射定量相分析方法,利用这种方法解决了铝电解质中阳极残渣(碳)浓度的测定困难问题。该方法分析数据准确度高、速度快,可以实现铝电解质中阳极残渣浓度的在线监控,降低了铝电解生产的成本。这种分析阳极残渣方法可以与全铝电解质分析技术共同组成一个软件包,在测试铝电解质中阳极残渣的同时,在3 min内还可以完成铝电解质中分子比、氧化铝、初晶温度、氟化锂、氟化钙、氟化镁、氟化钾、游离氟化钠、游离氟化钙以及亚冰晶石浓度的测定。
A new method of quantitative phase analysis of X-ray diffraction was studied. By this method, the determination of anode residue (carbon) concentration in aluminum electrolyte was solved. The method has the advantages of high accuracy and speed of data analysis, online monitoring of the anode residue concentration in the aluminum electrolyte and reduction of the cost of the aluminum electrolysis production. This method of analyzing anode residue can be combined with all-aluminum electrolyte analysis technology to form a software package. While testing the anode residue in the aluminum electrolyte, it is also possible to complete the aluminum electrolyte molecular ratio, alumina, primary crystallization temperature, fluorine Determination of lithium, calcium fluoride, magnesium fluoride, potassium fluoride, free sodium fluoride, free calcium fluoride and the concentration of sub-cryolite.
