摘要
探讨了试样先灼烧除碳 ,再加混合熔剂融熔 ,盐酸溶液中浸取 ,采取氟盐置换法 ,测定铝镁碳砖中三氧化二铝 ,终点易于判断 。
A new analyzing method that measuring the Al 2O 3 content in a Alumina-Magnesia-Carbon brick was introduced in this papers . When measuring with the new method,some mixed flux is added to the measured melt and it is leached by a HCl solution , after Carbon conter of the brick is burned. If measurement of Al 2O 3 in Alumina-Magnesia-Carbon brick by the fluoride displacement ,the judgement of terminal point is easyer,and the results is satisfactory.
