摘　　要：试验了高铝质耐火材料中SiO2,Al2O3、TiO2、Fe2O3的系统分析方法，试样与混合熔剂在铂金坩埚中熔融，用稀硫酸溶液将熔块浸出，定容后分析，本方法操作步骤简便。分析速度快，分析成本低，分析结果准确，能满足日常检验要求。The systematic analysis method for SiO2, Al2O3, TiO2 and Fe2O3 in high-aluminum refractory was tested, the specimen and mixed flux were melted in a platinum crucible, then the clinker was leached with dilute sulphuric acid solution, and the analysis was carried out after the solution was fixed to a constant volume. This method has a simple procedure, a fast analysis speed, a lower analysis cost, a accurate analysis result, can meet the requirements of daily inspection.
