摘要
以过氧化钠为熔剂 ,于铁坩埚内进行快速熔融试样 ,熔块以水浸取 ,硝酸溶解盐类 ,对铁矿石、球团矿、烧结矿中二氧化硅、氧化钙、氧化镁、三氧化二铝进行系统分析。与国家标准方法相比 ,本法具有操作简便 ,准确性好 ,速度快 ,成本低 。
By using sodium peroxide as flux,melting sample in a ferric crucible quickly,and dissolving with nitric acid, SiO_2,CaO,MgO,Al_2O_3 in iron ore can be analyzed systematically.Compared with the national standard method,the proposed method has more advantages such as operating easily,good accuracy,rapid procedure,low cost,wide range of determination and so on.It has been applied to the systematic analysis in iron ores with satisfactory results.
